The number of sperm cells that form from a primary spermatocyte is, whereas the number of functional egg cells that form from a primary oocyte is

Smpermocyte are the male gametocyte or germ cells in the testes of animals that are engaged in meiosis.  From this germ cell population of cells is produced. The process is called spermatocytogenesis. During spermatogenesis, four sperm result from each primary spermatocyte. Then form these two four other are produced.  Oocyte on the other hand is the female germ cells.The poress is called oogenesis. The female germ cells produce a primordial germ cell (PGC), which then undergoes mitosis, forming oogonia. So,the number of sperm cells that form from a primary spermatocyte is two, whereas the number of functional egg cells that form from a primary oocyte is one.
