Trisomy (21, 18, and 13) & Nondisjunction Genetics 

I would like to add that NDJ in meiosis 2 can also give two cells with trisomy if the resulting cells ( i.e. the resulting 2 cells at the end of meiosis 1) both experience non-disjunction. Hence, non-disjunction in meiosis 2 can give 1 or 2 cells with trisomy.

Great video! Do one on translocations please!

More than amazing ♥️

everytime i watch a video i have no idea how there is only 1700 likes. This is GOLD!

These songs are great! Id suggest highlighting in red the associated letter or word on the left list then sing the song while looking at the list. Should help with retention. Thanks again!

Uve made it perfect and quite easier for me

Thank you again! Any videos on Microbiology coming?

Great video!

Very informative 💯

One of the best. Thank you

Thank you very much

Noww u come out with a vid the day after my genetics final

Edwards Eighteen chromosome trisomy, for german speakers: ä = ae -> Paetau has 6 letters -> Hexadactyly

Thank you

Please can you reupload water soluble vitamins please it’s my request

F'ing amazing. Thank you.

Gold. More

Best one❤

Please make a video on neurotransmitters! 😥

Down 4ALCH-OHOL & BEER: - 4 = 4% robertsonian and 4As signs and symptoms.

Ty so much sir :)

IMO all medical students learning about trisomy 18 and 13 should also educate themselves on how a poor prognosis can be a self-fulfilling prophecy, and how outcomes for both conditions are much better if they're given aggressive care rather than palliative care. Both are severe life-threatening birth defects, but if they can survive infancy and get surgical treatment of their most serious defects, their chance of survival goes up significantly. Both trisomies, in non-mosaic form, have been reported in multiple individuals who have lived to adulthood.

Thankyou

Can u pls add lab findings/values to this video?

Great Great Great!!!!!!!!

I would add an extra 'A' to your mnemonic for Alzheimer's disease

Wish you have a mnemonic for the labs 1st and 2nd trimester for Trisomies

Love ❤️ you

king

also omPhalocele in Patau is fairly high yield

i love you

he never uploaded for microbiology i have been requesting since months buzzwords or smthing i know skecty is best but i need one liner buzzwords he does the best videos

why trisomy occur only on 13,18 and 21 chromosome?

In the USA the legal drinking age might be 21, but in the UK it's 18. Which is one of the other options, so it could be confusing to use that mnemonic...

Woohooo

you forgot labs

lame mnemonic for trisomy 21, the other ones are awesome though

Thankyou
