Final answer:
Male and female gametes develop differently. Spermatogenesis in males produces four small, motile sperm cells, while oogenesis in females produces one large, non-motile egg cell.
Step-by-step explanation:
The development of male and female gametes, or sex cells, differs in several ways. In males, the process is called spermatogenesis, and it results in the production of four small, motile sperm cells.
These cells grow a tail and gain the ability to swim. In females, the process is called oogenesis, and it produces only one large egg cell from the four cells that stem from meiosis. The egg cell is not motile and is significantly larger than a sperm cell.
