Question

question 5 of 10
which statement describes what happens to the chromosome number during meiosis?
a. sister chromatids are pulled apart so that each daughter cell receives half of each chromosome.
b. the parent cell duplicates its chromosomes so that each daughter cell has double the chromosome number of the parent cell.
c. homologous chromosomes stay together so that each daughter cell has the same number of chromosomes as the parent cell.
d. chromosomes form tetrads that are then pulled apart so that each daughter cell has half the chromosome number of the parent cell.

Explanation:

In meiosis, homologous chromosomes pair up to form tetrads in prophase I. During anaphase I, the tetrads are pulled apart and move to opposite poles. This results in daughter cells with half the chromosome number of the parent cell. Options A - C are incorrect as they do not accurately describe the chromosome - number change in meiosis.

Answer:

D. Chromosomes form tetrads that are then pulled apart so that each daughter cell has half the chromosome number of the parent cell.
