WebDuring spermatogenesis ( sperm formation) germ cells are divided by meiosis. Germ cells have 46 ( 23 pairs) chromosomes. During meiosis, a single germ cell is divided into four daughter cells. Each daughter cell has a half number of chromosomes (23). These daughter cells convert in sperms after differentiation. Thus, each sperm cell is haploid.
