During sperm formation, spermatids:
A. contain the diploid number of chromosomes.
B. develop directly from primary spermatocytes.
C. develop immediately after the first meiotic division.
D. develop immediately after the second meiotic division.
Spermatogonia (diploid) grows into primary spermatocytes (diploid) and then secondary spermatocytes (diploid) after the first meiotic division. Secondary spermatocytes become spermatids (haploid) after the second meiotic division.
