Question 1

The two terms reductional and equational generally refer to which stages of meiosis (I or II)?

Question 2

Assume that a mating occurs between a female with Down syndrome and a normal 46-chromosome male. What proportion of the offspring would be expected to have Down syndrome? Justify your answer.
