Which if the following is not a source of genetic variation in meiosis? tetrad formation migration of centrioles crossing over the random lining up of chromosomes on the metaphase plate independent sorting of alleles into gametes
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:

Introduction:-
Meiosis is a process in which a single cell divides twice to produce four cells with half the amount of genetic material as the original cell. These cells are our sperm and eggs, respectively, in males and females.
One cell divides twice during meiosis to produce four daughter cells.
These four daughter cells are haploid, meaning they have half the amount of chromosomes as the parent cell.
Meiosis is the process through which human sex cells, or gametes, are created (eggs in females and sperm in males).
There are nine phases in the process of meiosis. Between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).
