Textbook Question
Chapter 11, Problem 4S
Aneuploid gametes are cells that contain the wrong number of chromosomes. Aneuploidy occurs as a result of nondisjunction, or lack of separation of the chromosomes during either phase of meiosis.
a. At what point in meiotic cell division would nondisjunction occur?
b. Imagine a cell had a diploid chromosome number of four. Create a diagram to illustrate the effects of nondisjunction of one pair of homologous chromosomes in meiosis I versus meiosis II.
