WebbMeiosis is the unique division of germ cells resulting in the recombination of the maternal and paternal genomes and the production of haploid gametes. In mammals, it begins during the fetal life in females and during puberty in males. In both cases, entering meiosis requires a timely switch from the mitotic to the meiotic cell cycle and the transition from … WebbAt the end of first meiotic division, the male germ cells differentiate into A Spermatogonium B Primary spermatocyte C Secondary spermatocyte D Spermatid …

The small polar body eventually deteriorates. The secondary oocyte begins the next stage of maturation. Ootid The oocyte now begins the second phase of meiotic cell division.
