I so much appreciate this AncestryDNA channel. Thanks!

[@SuperManning11]

Extremely informative, thanks. I'm going to have to watch it again-maybe on an iPad, while I have the laptop open to my page so I can follow along. Your patience in explaining this stuff is much appreciated.

[@ruthwright6247]

Thank you so much for explaining how Ethnicity dna results works......I know DNA does not lie period. Thank you for your expertise!

[@Rony2453]

I did not know the state should not be abbrev. in our tree. News to me and I have been working on tree for many, many years! thanks.

[@LIGHTOTS]

I Love IT!!!!! Thanks again.

[@shawnjonessr.3902]

I have a question how accurate is the findings ? and can the testing come back with other on the chart . if so why is the percentage that's label other not found ?

[@mwinyimwenyi]

Why are Horn of Africa (Ethiopia, Somalia) grouped or in the South Eastern Bantu genetic region? Can you explain why you include them in he south Eastern Bantu?

[@kathleenthompson6007]

What if you have a half sibling and you link to the other side of the family in the hints?

[@Emy53]

I have found that people married into each others families. I have cousins that are related to me on both sides. They are distant cousins, but we know from family elders that cousins from my moms family married cousins from my dads family. It gets complicated for sure.

[@AncestryUS]

Thank you for sharing with us!

[@christinacastillo313]

I had my DNA analyze and I'm a little over 50% Native American. My question is, If Native Americans came from Asia, why do i only have 1% Asian?

[@AncestryUS]

The AncestryDNA ethnicity estimate gives you a look at the DNA you inherited from ancestors who lived 500-1000 years ago.

[@Emy53]

My son and daughter have different percentages on my side. My son took more of my husband's DNA, and my daughter took more of my DNA. They both share the same regions, but their percentages vary alot.

[@AncestryUS]

Hi, Amelia. Sometimes our DNA results will be a bit different than what we expect the results to look like, this is because we establish baseline ethnicity for our DNA test from contemporary people with known roots in a specific region. The 56,580 people whose DNA is used to establish baseline ethnicity is called our reference panel. What you get for your DNA results may be different than what you would expect them to be according to your family history, even histories proven through paperwork or other means. The results of this test are entirely based upon what you've inherited from both lines of your family with the information we have collected up to date. What you do inherit from your ancestors is randomized by genetic recombination, which may be the reason for differences in what you expected to inherit. You may find additional information regarding inheritance here: support.ancestry.com/s/article/Unexpected-Ethnicity-Results As DNA science improves, the number of regions we test for (and the countries covered in each region) may change in an attempt to narrow down the results to more precise locations. To understand how we determine your ethnicity, please view the article below: support.ancestry.com/s/article/DNA-Reference-Panel

[@Emy53]

@@AncestryUS Thank you very much. I have been keeping our family tree for several years. I am learning as I go so it's great to have channels such as yours for information and learning. I appreciate what you do.

[@stingrayofcincinnati]

Or how about this one. Why doesn't my cousin show up on my list of matches? He tested with XYZ company. LOL I love that one.

[@Emy53]

So they asked randon elderly people to test so they can begin a data base?

[@oldpirate8080]

26:38 -- I would love to be able to search matches and order them by relationship. List them in order of relationship.

[@AncestryUS]

Your DNA matches are in order based on relationship (ie. the amount of DNA they share with you). Those highest on the list share the most DNA with you. As you go down the list, they share less and less.

[@patrickmattes4935]

I have a sister and brother who share the same Mother as I do, but different fathers. Is it worth having them tested? OR should I only have my Sister tested for the Matrilineal side?? I have been doing Genealogy research on my family for nearly 15 years (have no contact with birth/BIOLOGICAL parents for 20-40 years).Thank you for so many informative videos.

[@AncestryUS]

Hi Patrick. You only got 50% of your mother's DNA. That means that there is 50% of your mom's DNA that you didn't get. Testing one of your siblings (who also got a random 50% of your mother's DNA) would give you about 75% of your mother's DNA to work with. Testing a 3rd sibling, means you will be working with about 88% of your mom's DNA. So, if you want to use your DNA Matches, and those of your siblings, to make new family history discoveries, the more of you that test, the more possibilities there are for discovery. Hope that makes sense.

[@chrisgrant4720]

Perhaps someone paid for their tree to be private?

[@stevenm73]

How do endogamous populations like the Amish and Mennonites affect the DNA results and cousin matching? I have been contacted by several cousin matches that were adopted as infants and know nothing or next to nothing about their birth families but are really hoping I have the answers they have been searching for. All I am able to determine is that yes, we are related but I can not say what side of the family we are related on. My parent's lines criss cross several times at various points. It is very important that these concerns are addressed for those of us that are descended from these populations that have intermarried within their religious groups like the Amish have since they began centuries ago. Now, when an Amish or Mennonite couple marry, they are marrying their cousin. PLEASE help us with this issue. I bought most of the kits for my family to be tested and as it stands now, I have spent hundreds of dollars getting myself and my family tested and beyond our ethnicity estimates, it sits there useless to me and my family . . . .

[@brittanymcneely6109]

If I were to do the DNA test, can I find out if I have Native American in myself? My dads mother had an Aunt that was supposedly Native American(Cherokee) and I've been wondering my whole life of its true (: I have the physical characteristics but there's no real proof but some documentation but I have never seen it haha.

[@AncestryUS]

+Brittany McNeely (The Little Sea Nymph) The AncestryDNA test does provide Native American as an ethnicity, where it exists.

[@megkallas8117]

Recently my brother took the Ancestry DNA test and as expected we were matched as siblings however, it indicated we could be half-siblings. Is this a normal comment or is this a new discovery? While I am fine either way, I wonder if this is a confirmation. How would we confirm he is half or a full sibling?

[@shaffy856]

You would have to test your parents

[@manniesreactionchannel3808]

I took my dna ancestry a year ago , I’m 1% France, 3 % Ireland 3%, Scotland 1 % Indigenous America’s north ... I’m guessing that’s a form of Native American. This dna thing is very interesting. I’m mostly meeting a lot of my Irish relatives. And I got some relatives who are related to some celebrities that I could be possibly related to.

[@apgeneticgenealogylover204]

Ancestry, it's been 2 years since the last ethnicity update when you added new reference populations. Of course, I can understand if you haven't added any new reference populations every six months, bu *TWO YEARS* should be enough time for you to have an update. An update is long due, ancestry. Come on.

[@apgeneticgenealogylover204]

+John Weston No. Both ancestry.com and 23andme have said they don't have a timeline on when they'll finally update their ethnicity portion. Tribecode just opened late last year, so I don't expect them to have one anytime soon. So far the only company that has updated is Geno 2.0 who now have "Geno 2.0: Next Generation" (why not a "Geno 3.0?"), which I still haven't seen any reviews of. On Roberta Estes' "DNA Explained," dna-explained.com/2015/11/18/2015-family-tree-dna-11th-international-conference-the-best-yet/ Family Tree DNA's 11th international conference says that Razib Khan (whom I don't really think very highly of, since he has been involved with some far right wing people, and I also don't understand why he, of all geneticists, was brought on by FTDNA to do their so-called "update" from the Population Finder) is talking about an update to the very terrible and underwhelming "myOrigins." The page says that this is supposed to happen in "due out in mid-late first quarter of 2016." It looks like there's supposed to be a new cluster aka category (mistakenly referred to by Roberta Estes as "reference population") for NA, but there's nothing saying on what the actual reference populations are. So far, this is the only thing I've seen on an update to the ethnicity portion at any of the companies unless you count Geno.

[@apgeneticgenealogylover6601]

+SyalomarPum Definitely. I think that if Centrillion Biosciences' Tribecode could use all of the available (North as in Chinese, Japanese, and Korean) East Asian available, then ancestry.com should have been able to too. However, I still don't expect any company to have any kind of specificity in Southeast Asia (Thai, Filipino, Vietnamese) for a long time. With Native (or rather Indigenous) American, I'd like to know when Dr. Carlos Bustamante's Mexican samples will be used by any of the companies.

[@apgeneticgenealogylover6601]

+SyalomarPum I meant "available" as in what's from Human Genome Diversity Project (HGDP) and 1000 Genomes. I think by far the most ridiculous was Family Tree DNA "myOrigins" I've read that they're supposed to update their ethnicity too, but I only expect them to work on the European and do some work, because of Razib Khan, for South Asian. I think they're going to leave East Asians and Africans untouched, but I think they are claiming that they will split North and South America apart. I don't know how they're going to do that without more of the same old five HGDP Indigenous reference populations. I emailed them to ask about this new update twice over the last two weeks and they haven't responded and I don't think they will.

[@TheSledge77]

What relation would a person be to their mothers 1st cousin. Would that be a 1st cousin once removed because the mothers cousin is one generation before the person who took the DNA test?

[@AncestryUS]

Hiya Dave, and thanks very much for stopping by lately! We know it can be tricky to work out exact relationships from time to time. We actually have a fantastic video from Crista that we think should be able to answer your query: kzbin.info/www/bejne/hWqYp6V9qJWjb8U We hope this helps a little in getting the answers you need, and we wish you all the best in your continued research!

[@frankhooper7871]

One of my 4th cousin matches (actual relationship is 5th cousins) and I only have one shared match: her son. However, her son and I have two additional shared 4th cousin matches. Another of my matches and I have 17cM of shared DNA, but her daughter and I share 24cM. Do these results imply that we're probably _also_ related on their father's side?

[@AncestryUS]

At that small of an amount of shared DNA, I would hypothesize that it is more likely that you are only related through the mother's side of the family tree. It is just likely that some of the shared DNA has been filtered out through the Timber algorithm that Ancestry applies in order to downweight segments of DNA that appear to show up in what we call "pile-up" regions. You can read more about that here: blogs.ancestry.com/ancestry/2015/06/08/filtering-dna-matches-at-ancestrydna-with-timber/

[@shellisherwood]

I had my father tested tested thru ancestry,com a few years ago, ydna and mtdna. He has since passed away, and I completely bummed that after paying over 400 dollars none of that information is useful with ancestry any longer. I called ancestry last week and was told " go find a company who will accept those results", so far everyone I have contacted with not accept ydna or mtdna. Completely let down by ancestry and their inability to assist me after spending all that money a couple years ago and since then my father has passed away. I did the test to try to find relative we should have in Spain.

[@cheryltoach8441]

if I have a public tree and put in my children's info they are still living can people that view your tree see their information. This is my confusion so I haven't yet put my children in my tree. My husband both my daughter and myself have just recently sent in our DNA still waiting on results.

[@ShahrinRahman]

It shows as private. I opened up my husband's account and he can't see my info and I can't see his info. However, if your children's name might show up in a public record. If any of your family member adds your children's name to their family tree, they will be able to receive a hint with your children's name.

[@France2107]

The DNA results that are available currently is really only useful for comparing to another family. For instance, if you have hit a brick wall in a certain line and there are several different prominent lineages of the same name, DNA can pinpoint which family you come from in order to concentrate your investigation in the right family line. DNA results come from only two people in each generation. Your father's patriarchal line and your mother's matriarchal line. So by the time you go back eight generations, which would be your g-g-g-g-g-grandparents, you have 256 persons and only two are counted. Each generation you go back, the number of people are doubled, and only two are counted in the DNA sequencing. So the ethnicity of your DNA test is only about 1% or less of what you actually are. Which is why you can know you have say Native American blood and yet have it not show up in your DNA results. Plus, parents only give a random 50% to each child, which is why the DNA of full siblings will not be the same. The 50% DNA you received from say, your father, will most likely not be the same as the 50% your sister received (unless you are an identical twin).

[@AncestryUS]

+France2107 Your understanding of genetic inheritance is mostly correct. You do inherit 50% of your DNA from each of your parents. They inherited 50% of their DNA from each of their parents and so on. So, on average, 25% of your DNA will be from each of your 4 grandparents. About 12.5% of your DNA will be from each of your 8 great-grandparents and so on. Now, due to the randomness of inheritance, the math may not work out exactly that way once you get beyond your parents. But, at a 5th great-grandparent level, even though there are 256 of them, you likely have DNA from far more than just 2 of them. Hope that makes sense. (Crista)

[@AncestryUS]

+France2107 Your information is correct if you are talking about YDNA testing (paternal only) or mtDNA testing (maternal only). Ancestry does autosomal DNA testing, which looks at everything you inherited from both parents and what they inherited from both of their parents and so on. You can learn more about this at about 9:30 in this video: kzbin.info/www/bejne/jHeliX-Xjs-NqMk

Thanks for stopping by, Malinda. We appreciate your interest in Ancestry and will be happy to provide some additional information. We have attached a couple articles below with an overview of what's included in AncestryDNA and some tips on how to use this product to look for your unknown biological family, should be something that interests you. First, the DNA test we offer in an autosomal DNA test, which is ideal for tracing now living biological family members. Many of our members do take part in AncestryDNA with the aim of locating biological family, and many are successful and especially when it comes to close relatives like a biological parents. However, we always want to be clear that there's no guarantees what you may find as it depends on who you may match with. This said, most people have hundredth of matches. When you take an AncestryDNA test you will be linked with everyone else in our database that share DNA with you across your biological maternal and paternal lineage, and by reviewing them you may be able to locate links with your biological parents and get in touch.

[@pippaliciousj]

This may be a stupid question but is it possible to tell if my youngest two kids have DNA from the Mediterranean area as they both tan so well as do their dad? If one or both did the test could it show the area where a part of the dad's line could be from?? We are in the UK and born here but I keep saying to the girls I swear there's a long distant line going back to the Med or somewhere lol. Sorry if I'm talking stupid.

[@pippaliciousj]

My eldest 2 kids have a different father. Only my youngest 2 go tanned brown really well.

[@AncestryUS]

Yes. You could test one or both of these children to get an ethnicity estimate for them. Italy/Greece is included as one of our ethnic regions.

[@kaligrl06able]

What if I don’t have my Mom anymore? Can I test her sister? No they are not twins. Just asking…

[@AncestryUS]

Hi Kaligrl06! Thanks for commenting your query, we're happy to address it. Anyone at all can take an AncestryDNA test, so you could absolutely get your aunt's DNA tested if you would like, however she would not be as close of a genetic match to you as your mother unfortunately, as you share around 50% of your DNA with a parent, but only around 25% of your DNA with an aunt.

+Barb5205 Simpson If she is showing up as a close family member, then yes. It is very likely. Click on her name to view the match page. Then click on the little (i) icon next to the relationship. If she shares approximately 1700 centimorgans of DNA with you, then she is your half-sister.

[@ShahrinRahman]

@@AncestryUS Wow that's really good info.

[@esterixis]

Just watching this video (out of order, obviously). My question has to do with the 4th-6th cousin matches (450+). I've clicked on all of those with public trees to find the possible matches (surnames), with no success. The majority of these surnames are Western European (I'm Native American/Iberian peninsula/Cameroon), & to the best of my knowledge, direct ancestors didn't marry Europeans. Even the Hispanic surnames don't match to the records I have. So, do they fall into the "random ethnicity/match" category? Having a hard time wrapping my head around this....

[@AncestryUS]

Start with the top matches on your list. They are the ones that you share the most amount of DNA with and are, therefore, most closely related to. Once you figure out how you are connected to them, you can use the Shared Matches feature to start to sort out your other matches by various branches of your family tree. So, how many centimorgans of DNA do you share with the top three matches on your list?

[@chickychikita]

17:25 they said surnames change .lol I was wondering that My maiden name is chinese my surname now is Italian ( husband ) lol so I hope they dont try to match the surnames that way ..lmao

[@historyoflanguages]

I'm wondering. Along with your kit, do they ask any racial/ethnic background questions? If they do, how do I know they're not going to use that and make shit up? For example, if I say I'm Cuban (which I am not), how do I know they're not just going to use historical data rather than DNA analysis and then be like "Ohhh yeah you're uhhh, 40% Iberian, 40% African, and uhhhh 20% Indigenous American. Yeah that sounds good, let's just tell him that! Sounds pretty historically accurate! And as a matter of fact let's throw in some Italian ancestry in there to spice things up and make sure we don't get caught lying to this sucker!" I ask because it would be much more impressive if they could pinpoint those locations without any self-reporting!

[@Lovelezlie]

+Tattooed Taino my brother purposely gave no background info for this reason and the results that came back made perfect sense given what we know.

[@mandlerparr1]

+Tattooed Taino They don't ask anything like that.

[@FlixChick]

+mandlerparr1 They don't ask for this info outright but if you link your sample to your Ancestry family tree it asks you to identify yourself in the tree. They get this information from your tree. If you do not have an Ancestry family tree then they really have no way of knowing.

My ex was supposedly adopted. We have a child. There is reason to believe that his aunt is in fact his birth mother. His 'adoptive' mother is deceased.

This suspicion is not known by the ex or family other than our daughter.

I got my DNA match a few weeks ago I'm 97% European in all and 21% Scandinavian witch is Norway and Sweden i understand . it said I was 41% Irish but the region included Scotland so am part Scottish? The oral history was we were Dutch that moved to Scotland then moved to northern Ireland for the king of England being a Protestant and then to America in 1674 in Baltimore. I got off track, my question is can the Ireland and Scottish be separated?

[@indigoblueviolet]

Is it possible for the offspring of two biracial people who are say each half Black (sub saharan african), and half White (northern european) to have children that are all white and all black because a child inherited all the White DNA or all the Black DNA from their Bi-racial parents? I do know that something like this happened in South Africa in the 60's where two White parents had a Colored child and they wanted to separated them do to the apartheid rule.

[@AncestryUS]

It is mathematically possible but highly unprobable.

[@siobhanobrien78]

My understanding has always been that two White people cannot have a Black child but two Black people can have a White child. That is what happened with my great grand parents . My grandfather was Black but his brother was white. Same mother . We know it is the same father because all the men in my family on my father's side of the family tree have the same distinctive right ear.

[@geographicoddity9444]

I have a question. Will a biological grandchild ever NOT come in as a match?

[@AncestryUS]

No. A biological grandchild will always show up as a genetic match to the grandparent.

[@ashleighwatson3084]

I have no dna cirlces and no ancestor discoveries even though I have over 100 shared ancestor hints and have more than 3 of them sharing a person in my tree and they are public trees.

[@AncestryUS]

Here are a couple of things to consider: 1. Is your tree public? You might want to double check that. 2. Do you have at least two other matches who are descendants of two different children of your common ancestor than you do? Meaning, for example, if your great-great-grandparents had five children, are there descendants of at least three of those children who have DNA tested and show up with Shared Ancestor Hints to you. 3. And, have you verified with those matches that they also match each other? If they only share DNA with you, you won't get a circle. They have to also share DNA with each other.

[@ashleighwatson3084]

Ancestry how do I verify or conferm it I read them and it's a match.

[@AncestryUS]

You would need to check the SHARED MATCHES with one of them to see that the other shows up on the list. Then you would need to contact them and ask if they have a SHARED ANCESTOR HINT to each other.

[@afropuffs5228]

why do they only match mongoloid native american ancestry and not the indigenous Africans (black people) that were living and trading there hundreds of years before slavery?

You only pay for a subscription to Ancestry if you are interested in accessing the 20 billion+ historical records we have available to you so you can build out your family tree and make more discoveries. You do not need an Ancestry subscription to access your DNA results, see your DNA matches, communicate with those matches, build an online family tree, or request access to the family trees of your matches.

[@LB-me4ch]

I believe in the ethnicity results. However, there is something fishy going on with the cousin matches. The second part of the results. Seems like the connection is based on other peoples trees.

[@AncestryUS]

If someone shows up on your DNA Match list, especially if they are a 4th cousin or closer, are most certainly genetically related to you in a genealogically discoverable time frame. When you say that there is "something fishy going on" what do you mean?

[@LB-me4ch]

I have a biological father who I never met who I was told was from Yugoslavia. I never disclosed this information to ancestry nor did I include it in my family tree. I got my Dna results back last week. I had 32 % eastern european which was suppose to be my highest ethnicity result then 21% British. Then other ethnicities 7%. No point mentioning the lower scores. What is bothering me is that I received 460 cousin matches and all had no slavic names. All British and English. Some French. I should have some slavic cousins given my Dna results. I hope the cousin matches have no connection to other members trees. It appears that's the case though.

[@AncestryUS]

If your biological father was born in Yugoslavia, it could just be that none of your Eastern European cousins have taken the DNA test yet.

[@LB-jn2gu]

[@ShahrinRahman]

It's for them to know and for you to research about. You can't expect scientists to give out every critical data out to the public. It's like asking how does a plumber fix the sink? Geneticist researches their information.
