gonads
At the end of meiosis, haploid cells are produced. These cells need to further develop into mature gametes capable of fertilization, a process called gametogenesis Figure below . Animals produce gametes directly through meiosis in organs called gonads. Gametogenesis differs between the sexes. In the male, the production of mature sperm cells, or spermatogenesis , results in four haploid gametes, whereas, in the female, the production of a mature egg cell, oogenesis , results in just one mature gamete.
