Compare the processes of spermatogenesis and oogenesis
Compare
Contrast
Spermatogenesis
Takes place in the testes ("Gametogenesis")
Involves an equal division of cells ("Gametogenesis")
Germline epithelium is involved in the gamete production ("Gametogenesis")
Four gametes produced
The size of the sperm (gamete) is smaller than the spermocytes ("Gametogenesis")
Process begins at puberty and is uninterrupted
The release of the sperms is continuous at ejaculation ("Gametogenesis")
Process is lifelong ("Gametogenesis")
Contrast
Oogenesis
Takes place mostly in the ovaries ("Gametogenesis")
Involves an unequal division of cytoplasm ("Gametogenesis")
Germ line epithelium IS NOT involved in the gamete production ("Gametogenesis")
One gamete is produced along with 2 or 3 polar bodies ("Gametogenesis")
The size of the gamete (ova) is larger than the oocytes ("Gametogenesis")
Process begins in the fetus and takes place in arrested stages ("Gametogenesis")
The gamete is released monthly according to the menstrual cycle ("Gametogenesis")
Process ends in menopause ("Gametogenesis")
Both involve cell growth before meiosis
Both involve 2 divisions of meiosis
Both begin with mitosis
