Web14 apr. 2024 · In mammals, spermatogenesis is a stepwise process including proliferative mitosis and meiosis, followed by a massive remodeling of the chromatin that is unique to haploid phase of spermiogenesis ... WebMeiosis is a set of two successive divisions in which the chromosome number is reduced from diploid (2N) to haploid (N). Meiosis thus differs from the simple division we imagined above, by the occurrence of one additional division. It is during this division that chiasmata are established between homologous chromosomes.
