6. Describe the ways in which cogenesis differs from spermatogenesis.

Oogenesis is the production of matured ''ovum or egg'' from a female germ cell. In females, from the primordial germ cells, oogonium is formed by mitotic divisions. '' Spermatogenesis'' refers to a process, in which a matured ''sperm'' is produced from a male germ cell.

The primary Spermatocyte undergo two meiotic divisions to produce a matured, which contains haploid number of chromosomes. Each Spermatocyte produces four Spermatids; in all of them, the chromosome number is reduced to half.
