Suppose that diploid cells of the seminiferous tubules encounter errors during the cell cycle and mitosis. This results in the primary spermatocytes having a 4n number of chromosomes. Assuming that meiosis proceeds normally, which of the following would be true?
A) Sperm cells would have an n number of chromosomes.
B) Sperm cells would have a 2n number of chromosomes.
C) Secondary spermatocytes would have a 4n number of chromosomes.
D) Secondary spermatocytes would have an n number of chromosomes.

Quizplus · Accepted Answer

If primary spermatocytes have a 4n number of chromosomes, then after the first meiotic division, secondary spermatocytes will have a 2n number of chromosomes. After the second meiotic division, spermatids will have an n number of chromosomes, resulting in sperm cells with a haploid (n) number of chromosomes. Therefore, the correct answer is B.
