| Description: 1 A male germ cell develops into a primary spermatocyte as it replicates its DNA. Both types of cell are diploid. 2 Meiosis I in the primary spermatocyte results in two secondary spermatocytes, which are haploid. 3 Four haploid sper- matids form when the secondary spermatocytes undergo meiosis II. 4 Spermatids mature as sperm (haploid male gametes).
