Textbook Question
Chapter 13, Problem 6A
During the process of spermatogenesis, a nondisjunction event that occurs during the second division would be
a. worse than the first division because all four meiotic products would be aneuploid.
b. better than the first division because only two of the four meiotic products would be aneuploid.
c. the same outcome as the first division with all four products aneuploid.
d. the same outcome as the first division as only two products would be aneuploid.
