The three main stages in gametogenesis are proliferation, meiosis, and differentiation. During proliferation, germ cells undergo mitotic divisions to increase their numbers. In meiosis, these cells undergo two rounds of cell division to reduce the chromosome number by half, resulting in haploid gametes. Finally, in differentiation, the gametes mature into functional sperm or eggs, acquiring the necessary structures and capabilities for fertilization.

Three key differences between mitosis and meiosis are: Mitosis results in two identical daughter cells, while meiosis produces four genetically unique daughter cells. Mitosis occurs in somatic cells for growth and repair, while meiosis occurs in germ cells for sexual reproduction. Mitosis involves one round of cell division, while meiosis involves two rounds of cell division.
In order to increase genetic variance both egg and sperm undergo meiosis, which results in 4 cells. In oogenesis most of the cells cytoplasm is conserved by one cell known as the ovum. This increases the chance of fertilization and survival of the egg. The remaining three cells are the byproducts of meiosis and are known as polar bodies. They are eventually degraded.

Four gametes are produced every time a cell goes through the process of meiosis. For females, the four become an egg(zygote).
The three key differences between mitosis and meiosis are: Mitosis results in two identical daughter cells, while meiosis results in four genetically different daughter cells. Mitosis involves one round of cell division, while meiosis involves two rounds of cell division. Mitosis is involved in growth and repair of body cells, while meiosis is involved in the production of gametes for sexual reproduction.
The three major differences between mitosis and meiosis are: Mitosis results in two identical daughter cells, while meiosis results in four genetically different daughter cells. Mitosis involves one round of cell division, while meiosis involves two rounds of cell division. Mitosis is involved in growth and repair of body cells, while meiosis is involved in the production of gametes for sexual reproduction.
The three outcomes of meiosis are genetic diversity through crossing over, haploid cells with half the number of chromosomes as the parent cell, and the formation of four genetically unique daughter cells after two rounds of cell division.
Meiosis results in four haploid cells. In the female mammals, only one of the three cells will become an ovum. In males all four haploid cells will become sperm cells.
Cells formed by meiosis are called gametes, specifically in animals and humans. In males, meiosis produces sperm cells, while in females, meiosis produces egg cells. Meiosis is a type of cell division that reduces the chromosome number by half, resulting in genetically diverse gametes for sexual reproduction.
