Meiosis is the nuclear division of diploid cells into haploid cells, which is a necessary step in sexual reproduction; it is a significant chance to introduce genetic diversity into gametes. Sexual reproduction is the production of haploid cells (gametes) and the fusion (fertilization) of two gametes to form a single ...

WebIn mammals, the first part of oogenesis starts in the germinal epithelium, which gives rise to the development of ovarian follicles, the functional unit of the ovary.. Oogenesis consists of several sub-processes: oocytogenesis, ootidogenesis, and finally maturation to form an ovum (oogenesis proper). Folliculogenesis is a separate sub-process that accompanies … WebMitosis and meiosis both involve cells dividing to make new cells. This makes them both vital processes for the existence of living things that reproduce sexually. Meiosis makes the cells needed for sexual reproduction to occur, and mitosis replicates non-sex cells needed for growth and development.
