What processes are responsible for the generation of genetic variation during meiosis, and at what point in meiosis does each occur? Random alignment and separation of homologs that takes place during metaphase I and anaphase I, respectively. Independent assortment of homologous that takes place during anaphase II. Crossing over of non-sister chromatids that take place during prophase I. Replication of DNA during the S phase.

Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
