Oogenesis, Biology

Assignment Help:

- Oogenesis involves the formation of haploid cells from an original diploid cell, called a primary oocyte, through meiosis.

- The female ovaries contain the primary oocyte. There are two major differences between the male and female production of gametes. First of all, Oogenesis only leads to the production of one final ovum, or egg cell, from each primary oocyte (in contrast to the four sperm that are generated from every spermatogonium).

- Of the four daughter cells that are produced when the primary oocyte divides meiotically, three come out much smaller than the fourth. These smaller cells, called polar bodies, eventually disintegrate, leaving only the larger ovum as the final product of Oogenesis. The production of one egg cell via Oogenesis normally occurs only once a month, from puberty to menopause.
