My goal is to reduce educational disparities by making education FREE.
These videos help you score extra points on medical school exams (USMLE, COMLEX, etc.)
For educational purposes only; NOT medical or other advice.
Some videos contain mild profanity and hyperbole solely used to assist with memorization. Viewer discretion advised.
Opinions are entirely my own.
The pedigree examples at the end (example #1 and #2) were not proofread by a geneticist. I made them quickly just to illustrate visually what rule #1 and rule #2 may look like on a real pedigree. Obviously the other sex offspring not included in the relevant rule might be affected, but for simplicity sake i made them non-affected in the examples. This is not intended to be used to learn the nuances of genetics, this is to get points right on test day.
TL:DR - just memorize rule #1 and rule #2 if you want to get all X-linked pedigrees correct.
Mnemonic for X-linked Dominant:
X-linked *D*ominant = affected *D*aughters from affected *D*ads
pls make pedigree videos for ad n ar pls
thank u very much that was helpful....i have a Q .... can X-linked inhe come from a carrier? u didn't give us this example
Thanks Dirty!
Also shouldn't X-linked recessive be affected sons from unaffected mothers?
Thank you !!! This made it easier to remember @@abuilsult
I usually think Dad-Daughter->Dominant (DDD). Thank you for the video.
Thank you. It was helpful 👍🙂
thanks
It helps
Good one! 👌
Excellent
Awesome as usual... Happy 2020, Dirty! And good luck for all the ones that are taking the test this year.
Damn you made something thats usually really complex to understand, easy thanks man !
I've been confused about x-linked pedigrees for a while, thank you for making this so clear.
This was so helpful. Thanks a lot Dirty !!
Excellent and I think the most easiest way to overcome in understanding x linked diseases
This video is great! Can you make one for AR and AD please?
this helps me understand the X linked pedigree! thank you!
Thank you so so much for making this video!!
thanks a lot. I was really struggling, I really appreciate your tips.
Excellent Video, thank you.
Thank you so much! God bless you!
please also explain the chance of carrier carrying the gene , most of the quests are also related to this c
Thank you so much ! Exam in two hours I needed this
Awesome video! Thanks for the explanation:)
Please do explain the CARRIER GENE phenomenon too for XD and XR scenarios
since most of the people nowadays perform ASMR video, It is helpful to use it in MB exam:
ASMR;
Affected
Son
Mother
Recessive
Thanks for this quick revision shot on Mendelian disorder traits in the Pedigree chart.
Thanks from India 🇮🇳. Post more of this ❤
Hi, is this only applies from 1st generation to second one usually? or it is also applicable from 2nd generation to third one and then from third to fourth?
I did not get it in class and i expected it to be like super hard but it’s literally so easy! Thank u
right?!
This was so helpful, thank you so much!
This was a great explanation, thank you!
Thank you so much for this video! It helped a lot! I wish I watched this video earlier
Please make one on AR and AD too please!!
plssssss
Yeah please please please🙏🙏🙏🙏
Patiently waiting 😭
Still waiting 😢
Perfect!!
you're amazing.Thank you
Amazing, thank you!
Brilliant!
nice and clear. easy to understand!
This was the simplest version ever❤thanks DDF😅😅
YOU REALLY HELPED ME ALLOT , THANK YOU SO MUCH
God bless you
you made a mistake making the pedigree in the middle at minute 4:03 the sons should be dominant X and recessive X not both dominant. But other wise this is great. Thanks
have a gene exam tmr, this helped me a lot. thanks for the vid!
help me please
I have a biology quiz tomorrow on this tyyyyy for making it really easy 💗
You are theee best i love u. Thank u sooo much
You are a godsend thank you
Thank you so much 😊
this is so rad thank you
Need more videos on genetics please!
Best explanation
جزيت خيراً
Super easy concept I have ever watched thaks to you for your beautiful concepts helping ❤love from Ahad side ❤😊
YOU ATE!!!
awesome video as usual
About question 1 that u put..wasn't that autosomal dominant inheritance ???
thank you!!
Amazing
Amazing 😻
How we know whether its x linked or autosomal?
Soo helpeful!
In the second punnet square both of the sons have The Gene A (dominant allel) but why it’s not effecting them??
All the way from Ghana 🎉😊
I subscribed because u made it so easy for me now😭😭
Thank you
V nice explanation
thank you
Can u make video on confidence interval and hypothesis testing for biostat
As a general pedigree structure/composition rule, aren't males always on the left and females are on the right in a couple that mates (ie:// example 1)
really helpful!
amazing.
Thanks
very good video 😁
Is it affected mother or carrier mother for x linked recessive??
Thankyou soo soooo sooo much ❤❤❤
This video is MFly brilliant. 😅😅😅😅 luuuuuv it!!!!!
Thank u
thanks sir so easy lecture so so so thanks
Do u hv videos on how to solve all pedigrees
Make a t shirt with dirty med logo! I wanna buy!
The chart displayed at the very beginning....it is Autosomal recessive, right ???
how? shouldn't it be autosomal dominant
@@moob2020 yep dominant bec all the generation got the ds.
I have a pedigree where there is an affected father x wt female producing an affected daughter and unaffected son. But my professor stated all cases, autosomal dominant+recessive and x-linked dominant and recessive work here....but how cold I check for rule 2 here?
thankyou
Wait! In the X linked recessive one the third punnet square had two homozygous recessive females. Thaat makes the female affected right?
Thankyouuuuu
Thakyouuuuu❤❤❤
love u bro
FDD 🕺 MSR 🕺 FDD 🕺 MSR 🎶 🎶 my latino head already making a choreography in my head lol
Thank u sir it's really useful heartly thank u sir
nice
What is the correct option?
Thank you 🫂
Freaking entry exams into med school were harder than the med school itself :D
Really?
👍👍👍
heaven sent
So does that mean, affected mother cannot pass the affected allele to their daughters?
She does, mother shows equal inheritance while the father by transferring Y chromosome to son and X one to her daughter shows unequal inheritance. That was just an example for you to determine the possible genotype of parents in a pedigree.
What about carriers !!
So if the allele is recessive and affected sons don't come from affected mothers, can we say based on that info that the disease is not X linked? Someone please help
because this goes against what m teacher taught me.
👍🏿👍🏿👍🏿👍🏿
I LOVEEEEEEEEEEEEEEEEE YOU
what about X-linked dominant mothers?
Where are the explanation of next types
“Only Male from Uneffected parents” is also X linked Recessive???
it takes me 5 min to remember the diff between the circle and the square.
Dads are dominant over daughters X’s.
Mothers take their sons for Recess
