Has anyone bumped into any nondisjunction diseases on the DAT like klinefelter or turner where you had to know the genotype (XXY, XXX, etc.)?

I don't quite remember these things. Is Turner XO and klinefelter XXY? I think anything is possible even if other SDNers haven't seen them on their tests...

Yeah, I've always been bad remembering those...you have them right.

I Dont think you need to know the diseases names, just know that nondisjunction diseases are caused by 45 or 47 chromosomes.

Thanks for the replies guys...I've got the names rememorized now anyhow. 😉

yea I saw one about Down Syndrome, trisomy>?

2N+1 was answer?

Or was it 2N-1.

I cant remember.

Down Syndrome is trisomy 21, so I guess the answer would be 2N+1. Hopefully they're somewhat nice and stick to Down's instead of Tay-Sachs or something...

I don't think "Tay-Sachs" is a non-disjunction disease. Isn't it a genetic mutation that causes "GM2 ganglioside" to excessively accumulate in the brain due to the absence of hexosaminidase A?

I really hope you had to look up the details...now do you see why I don't want to be asked about...I don't know anything about it...

yes you do, you mentioned the name 1st 😉 mocha, I bet you'll get excellent scores for the real DAT. you'll do great. I just hope that I could be as motivated as you are. All I can do for me is "pray for luck" I have 20% chance to pick the right answer for each question. With a little bit of luck I hope that I can make that 20% chance 50% to at least get 17.5. With a little more luck I hope that ADA rounds up 17.5 to 18.
