What are the 4 Types DNA? | Genetic Genealogy Explained

[@paulorasantos]

Thank you for the video. Now I finally understand what recombination is. I had a wrong idea.

[@FamilyHistoryFanatics]

Glad it helped!

[@johnkhoury1759]

Thank you very much Andy Lee for clarifying a complex subject. JK Esq.

[@FamilyHistoryFanatics]

My pleasure

[@deckocards6988]

Thanks for the info! I hadn't heard about the X DNA and what it provides.

[@FamilyHistoryFanatics]

X DNA is usually lumped in with the autosomal DNA. Its sort of the bastard stepchild of the DNA world.

[@monmapisan4233]

very useful for my final test.

[@FamilyHistoryFanatics]

Hope you pass!

[@hamolina]

I read something about new theories on mitochondrial DNA being passed down by fathers every few generations. Maybe you have a update explaining how that might affect the traits that ate passed dow.

[@FamilyHistoryFanatics]

There have been a handful of cases found where people had paternal mitochondrial DNA. All of the cases involve people with mitochondrial disease of some sort. It is not a common thing in the least and doesn't change the general principles of DNA inheritance.

Hello, I don't know who my father is so how can I get the help that I need to find out about my family on his side!?

[@inazawakoreto]

I've been searching for awhile, what's the name of the gen or DNA when you don't look like your parents? Like, your parents both blond hair but you had black hair Or they had blue eyes and you had brown eyes I only remember this was part of elementary lesson but forgot what it was

[@BiloHazard]

really helpful Thanx

[@FamilyHistoryFanatics]

Most welcome!

I have a question. My brother is deceased since 2010. And I’ve never had contact with my biological Father. And my mothers biological birth family is unknown due to my mother being an adoptee. Could I use my brothers son’s (my nephew ) to find out the Y-DNA on my paternal side so I can try and locate biological family members?

[@FamilyHistoryFanatics]

Yes, your brother's son will have the same Y-DNA as your brother and your father. Also, take one of the Autosomal tests for yourself as well (and for your nephew), this can also give you some hints through cousin matching. For instance, those people who match both you and your nephew are most likely related through your father's line.

[@Beckie.B.LeeCountySWFL]

Family History Fanatics thanks so very much. :) this is all confusing to me. So thanks again. I submitted dna test for both my nephew and myself into Myheritage and also uploaded these to the GEDMATCH which that site is truely confusing to me. So I am watching all your videos and they are so very helpful! I’m learning from the videos.

[@Lynn-gee]

Ok, so in the case of a mutation in my mtDNA - are testing companies still able to assign my DNA to my mom's DNA? (If she has her DNA tested at the same company as me.) And if there were no mutations.. should not all (wo)men have the same mtDNA? I'm not referring to the genesis with Adam and Eve. I rather think about the time when the mitchondria entered the eucaryiotic cells. Or even further back when mitochondria started multiplying. Is it even possible to say that there was *the one* DNA, which just got altered over the course of time due to mutations, merging, invasion etc...?

[@FamilyHistoryFanatics]

Yes, what they would do is classify your haplogroup as a daughter haplogroup of your mothers. That is actually how all of the haplogroups are organized in a great big 200,000 year old family tree. Yes, if there were no mutations, we all would have the same mitochondrial DNA. And if there were no mutations all the way back to the first Eucaryiotic cells, then every eukaryote (Plants, Animals, Fungi, Amoeba, etc.) would have the exact same mitochondrial DNA. This is really cool to think about, because then we would have the same bit of DNA that organisms, 2.1 billion years old had. Too bad we have mutations.

[@FamilyHistoryFanatics]

I doubt that the "original" mitochondrial DNA is still around. There are a lot of human haplogroups that we know must have existed but don't anymore. All because of mutation.

[@Lynn-gee]

@@FamilyHistoryFanatics That's so fascinating.. I can't wait for the day they find dead cell material on Mars! Just imagine, how the media will freak out, if some similarities between the terrestrial and martial DNA will be found.

[@jeanmckenney6171]

What DNA test should I use to find out about my father’s maternal line? My father is still alive. He is 97 so I need to know what test should I have him take if I can only afford one. I also have a brother so I could do an Y DNA test on him at a later date.

[@FamilyHistoryFanatics]

Wow... KZbin finally surfaced this question. Sorry for the delay. You should test the oldest living relatives with autosomal DNA tests from Ancestry. Transfer that result to MyHeritage, 23andMe, FamilyTreeDNA and GEDMatch. Then being building your family tree based on genealogical records and then use DNA cousin matching from closet relative to most distant.

[@NoahDplayzz]

yo thx man im getting that extra credit

[@FamilyHistoryFanatics]

KZbin is great for assignments isn't it!

[@anneliesesullivan-wilson1038]

Have you done a video about understanding chromosomal comparison tools?

[@FamilyHistoryFanatics]

Do you mean the chromosome browser or are you thinking of something like DNAPainter?

[@anneliesesullivan-wilson1038]

@@FamilyHistoryFanatics sorry the browser.

[@anneliesesullivan-wilson1038]

@@FamilyHistoryFanatics I cannot get my head round the idea of comparing the DNA results of two matches.

Need some help.My friend lives in Asia. Never knew her dad. Has no idea what his ethnic background was. I read on some google searches that females cant trace their fathers origins/forefathers. Is this true? Pls advice on what test she should be doing.

[@FamilyHistoryFanatics]

The information you have is not entirely accurate. What they mean is females do not inherit y-DNA. But that doesn't mean you can not research your paternal line. You can find out a lot about all family lines back to the 4th generation using autosomal tests from MyHeritage, Ancestry, and 23andMe. The problem with folks who live in Asia is what company can they test with based on their country's restrictions on genetic testing.

[@MarinaGustsone]

Just curious, if my daughter has only one X chromosome (Terner syndrome), if we (my daughter, me or my husband) will make a DNA test in the future, will it show which X did she get? 🤔

[@bettyswurld]

did you get an answer to this question?

[@FamilyHistoryFanatics]

You would have to take an xDNA test for yourself and your daughter. Chances are that she got the X from you.

[@steveniruthaya]

Too bad if that uncle or cousin or brother is from cheater-rare but still chance that is not there DNA. how did we know that their real uncle or cusion or real brother? I am confused.

[@janettempest716]

Does this mean all men get from there father is his name and a daughter passes on fathers chromosome to her children ?

[@FamilyHistoryFanatics]

No. The men pick up the Y-DNA. See these videos kzbin.info/www/bejne/iGLbdIhvZsmDl7M kzbin.info/www/bejne/Zn6ydnusZsxraqc

[@ziggyutah]

One copy from each parent? Uh, half a copy from each parent?

[@FamilyHistoryFanatics]

One copy of each chromosome (or each set of genes) from each parent. Half of your DNA from each parent.
