I literally had to learn this for over an hour and understood 1 thing. I just watched a 4 min video and understood everything. Thank you for making this

People like you are the reason people like me pass classes, thank you.

Thank you Mrs Jennifer for making this easier to understand.... I’m taking college genetics Fall 2020...

[@faithroxy8282]

Thanks so much for this! Very easy to understand - most helpful video ive seen yet

[@spherebrothers]

Today I my College professor teach us pedigree building I didn't understand anything. After coming home I search KZbin and this 4 minutes video clear my all doubts. Thanks mam ..love from India 🇮🇳

[@kamhardee8558]

This video is so amzingly imformaive and it makes Pedigree Charts easy! Thank you so much! :) I learned more from this than any other videos on youtube, my teacher, and my tutor!

[@jrbrouwer5936]

very good video .... loud and clear!!!

you don't know how helpful this is!

[@gwiazdawilk5416]

It's been a while since I watched this! Nice video! :D This can help me a lot for making some reference charts so I can figure out how the different parts of family are linked together! Thanks for the video!

[@ashleybeck1974]

this by far THE BEST VIDEO in the WHOLE ENTIRE WORLD. I have my AP Biology exam tomorrow and you definitely helped me alot! thank you sooo muchhhh

[@sambasivaraovejendla5274]

Superb video! I love to watch the videos of native English speakers since they speak fluently with accurate pronunciation.

[@NightReads-d8z]

nice to see a video made 10 years ago helped me understand it . Thanks Jennifer. 🤝

[@konahflomo8808]

This is a brilliant way of explanating to students. Well done!

[@oliviayoung6568]

This video was so helpful! This topic is going to be on my major Biology test tomorrow, and because of this video I feel much better about it! Thank You for posting this!

[@ah0930]

appreciated, even more useful than what our teacher has been teaching for a month.

[@jewelthomas7086]

how did father to son transmission occur in x linked can u explain me????

[@jenniferdesrochers1640]

Hi Jewel- are you asking about the sex-linked example? Genes can be linked to the Y-chromosome and pass from father to son. X-linked traits can only be passed from an affected or carrier mother to son because the Y must come from the father. Let me know if you have further questions!

[@Anurag9344-q1i]

​​@@jenniferdesrochers1640hi ma'am at 3:54 this is an example of x linked dominant. Not autosomal. Lets say male= XY affected female = X'X . Then X'Y (affected male) , XY (normal male), XX' (affected female). Then affected female marries a normal male. Therefore XX and XX'.

[@alexisnimubona3141]

What a good teacher! I teach science somewhere! I appreciate the way you explain. god bless u

[@kyliepeel609]

i learned more in this video than i have learned all year thanks

[@MaryamShehab]

Very helpful and a quick solution for MQS exam questions thank you!!

[@energizer8888]

Awesome. I have one test left to take for my GED and it is the science. Another student who previously took the science test said a question like this came up on the science test.

[@MrSybertech]

Thank you this was very helpful! helped refresh my memory before an adv bio final.

[@MohammedAljubury]

3:45 shouldn't it be Y-Linked? because it didn't skip a generation and it only showed up in male (specifically all of the sons), so why was it X-Linked?

[@jdicey5552]

Mohammed Aljubury hemophilia is a recessive gene found on the X chromosome that affects the bloods ability to clot normally. As females have XX they will always end up with one functioning X chromosome that codes for correct blood clotting. Females with two dysfunctional X chromosomes result in a natural abortion. As males are XY they may end up with the recessive dysfunctional X chromosome.

[@athrishpanthati1156]

@@jdicey5552 Thanks!! even i had the same doubt.

[@patelrajen7354]

Oh yes it is a y linked

[@rishimaborah9956]

@@patelrajen7354 it is y-linked. if it was x-linked, then females should have got affected or would had been a carrier.

[@Anurag9344-q1i]

​@@rishimaborah9956nope. In the second generation normal female married normal male (if it was y linked then male would have been coloured)

Thank you very much for this video, this is such a great and simple video that gives a wonderful explanation on the topic and you taught it in a way that was very easy for me, Someone who is very much not that knowledgable on the topic to understand.

thanks for uploading this amazingly explained vidio. Ucan't imagine that a big doubt of us is tackled , thanks alot again

[@backstreetfan2887]

Fantastic video, thank you. I have one nit-picky comment. Instead of saying that the horizontal line indicates that people are married (1:08) I would have said "This horizontal line is called a marriage line, and it indicates that this couple had children together" because in reality parents are not always married to each other, and for the sake of studying biological inheritance, we don't need to make any assumptions. In any case, great explanation, thanks.

[@jenniferdesrochers1640]

Yes, I know! I made this video for English language learners a while back and had to phrase it less accurately than I wanted.

How to identify the older offsprings of generation 1 if their ages are not listed? Is the oldest from left to right on the same row? Since I have a question that ask about the oldest daughter but the generation 1 has two daughter on generation 2.

[@jinhengli8077]

Easy to understand. Do you have more about Pedigree Chart teaching videos ? Thank you Teacher.

[@shadymedhat9372]

Thanks for the great video! But AFAIK, the sex-linked diseases are always carried on the X chromosome so there is no male-to-male transmission as a son always inherits his X chromosome from his mother and the Y from his father so he isn’t affected by his father but the mother has to be at least a carrier for him to be affected. Hence, in the last problem the pedigree on the left can’t be a sex-linked disease since the mothers aren’t even carriers and the it’s male-to-male transmitted.

[@nolanharrington5439]

You're the best. Thanks for the video!

[@AbhishekBhal]

in pedigree on the left the trait should be Y linked as all males are effected not X linked, please correct me if i m wrong

[@zahrah4145]

it weird, x-linked affects all males but in x-linked recessive, it affects all females.

[@AbhishekBhal]

Zahra Hussaini i think its becasue females have two X chromosomes, so recessive affects females. And males have one X and one Y, so dominating effects males

[@zahrah4145]

yeah!

[@eidelweiss7850]

i agree

[@eidelweiss7850]

i agree, it shouod have been a Y linked sex trait
