Gametes are produced by meiosis - Both oogenesis and spermatogenesis
One primary cell produces four functional gametes - Spermatogenesis only(Because in oogenesis polar bodies are formed)
Production of all the primary cells occurs before birth - Oogenesis only( Spermatogenesis starts from puberty)
Meiosis finishes only after fertilization occurs - Oogenesis only
Gametes are relatively smaller than the primary cell that produced them - Both oogenesis and spermatogenesis

A difference between spermatogenesis and oohenesis is
Question 11 1 pts A difference between spermatogenesis and oogenesis is each primary spermatocyte produces 4 gametes while each primary oocyte produces one gamete. O spermatogenesis uses the process of meiosis and oogenesis uses the process of mitosis. O oogenesis is completed prior to fertilization and spermatogenesis is completed after fertilization. oogenesis continues from puberty until death while spermatogenesis occurs from birth until death.
