Which of the following statements best captures an aspect of normal spermatogenesis?
A) Testosterone chemically lyses each primary spermatocyte into two secondary spermatocytes with 23 chromosomes each.
B) Sertoli cells differentiate into spermatids, each of which can contribute half of the chromosomes necessary for reproduction.
C) Spermatogonia adjacent to the tubular wall undergo meiotic division and provide a continuous source of new germinal cells.
D) Each primary spermatocyte undergoes two nuclear divisions yielding four cells with 23 chromosomes each.

Question

Quizplus · Accepted Answer

The process of meiosis consists of two consecutive nuclear divisions of a primary spermatocyte with formation of four daughter cells, each containing a single set of 23 chromosomes. Testosterone does not chemically lyse immature sperm, and Sertoli cells play a nurturing and facilitative role in spermatogenesis rather than differentiating themselves into spermatocytes. Spermatogonia undergo mitosis, not meiosis.
