Text Solution

Verified by Experts

In males , at puberty the permatogonia (sperm mother cells) begin to undergo meiotic division and produces sperms through out life, whereas in females during the stage of foetal development , the germinal epithelial cells undergo mitosis and produce oogonia (egg mother cells) and they further enter prophase-I of meiosis -I forming primary oocytes and get arrested . No more oogonia is formed further. At puberty, out of million eggs (prime oocytes) produced at birth only 300-400 will ovulate till menopause.
