Gametogenesis is higly important for species survival and speciation. Spermatogenesis - male gametogenesis - can be divided in three phases: mitotic phase (when mitotic divisions take place), meiotic phase (with meiotic divisions and when cells became haploid) and post-meiotic phase (in which spermiogenesis occurs and there are haploid cells). Due to its particular characteristics, such a…
