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:
How meiosis can generate three kinds of tetrads when two genes are on different chromosome
Meiosis leads to the production of 4 haploid progenies when a diploid cell divides through it. Tetrads are spores, which are produced by lower organisms like fungi. Tetrad analysis is used to study the transmission of linked and unlinked genes and for other purposes as well.
