Summary Introduction

To review:

The four sperms for each primary spermatocyte are produced through spermatogenesis, but oogenesis produces only one egg for each primary oocyte. The reasons for these different outcomes that they might be adaptive.

Introduction:

Gametogenesis is a process by which haploid gametes are formed. The sperm and ovum are the male and female gametes, respectively, formed with the help of processes called spermatogenesis and oogenesis, respectively. The haploid gametes are formed from diploid germ cells. Spermatogenesis occurs in the seminiferous tubules of the testis and oogenesis occurs in the outermost layer of the ovaries.
