Happy new year everybody. What better way to celebrate the new year than doing some DAT Destroyer problems?
This is from the Bio section of DAT Destroyer, 2016 version. Problem #563. It gives two statements and asks T/F. I will include only the one statement I'm not sure about (the other statement is true without a doubt).
The statement reads:
If non-disjunction occurs during Meiosis 1 of anaphase, a trisomy or monosomy can occur b/c one daughter cell may retain both replicated chromosomes, while the other daughter cell lacks the chromosome. This would imply that haploid sperm cell can fertilize either cell resulting in a monosomy or trisomy.
I had wrote down Statement 1 is false, Statement 2 is true--the actual answer is that they're both true. Either means one or the other, not four. The wording makes it seem like it's saying the sperm cell can fertilize the daughter cells of Meiosis 1, when really it should be Meiosis 2, correct?
Any help would be appreciated.
