Question

In animal gametogenesis, a single primary spermatocyte generates ______ sperm, while a single primary oocyte generates ______ egg(s).

Answer 1

In gametogenesis, a primary spermatocyte produces four sperm through spermatogenesis, while a primary oocyte results in one egg through oogenesis.

Step-by-step explanation:

In the process of gametogenesis, which occurs through meiosis, a single primary spermatocyte generates four sperm, while a single primary oocyte generates one egg. During spermatogenesis, primary spermatocytes undergo two rounds of cell division to produce four haploid spermatids. Each of these spermatids matures into a sperm cell, capable of fertilizing an egg. In contrast, oogenesis results in one large egg cell and three smaller cells called polar bodies, which do not develop into eggs. Only one egg is produced because it retains most of the cytoplasm from the original cell, providing the resources necessary for the early stages of embryonic development.
