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.

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!

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.

Woohooo

[@prashantranjan9289]

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

[@DirtyMedicine]

it can occur on more than those chromosomes; these are the just the ones that show up on exams the most

[@shoshanahcohen3942]

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...

[@prathikmane1625]
