Question

how many useful gametes are produced in the meiosis of male animals? what about female animals?

Explanation:

In animal meiosis, male spermatogenesis produces four functional, haploid gametes (sperm) from one diploid primary spermatocyte, as all four daughter cells develop into viable sperm. In contrast, female oogenesis prioritizes cytoplasm allocation to one cell; only one functional haploid gamete (ovum) is produced per diploid primary oocyte, with the remaining cells becoming non-functional polar bodies that degenerate.

Answer:

• For male animals: 4 useful gametes (sperm) are produced per meiosis.
• For female animals: 1 useful gamete (ovum/egg) is produced per meiosis, with the other products being non-functional polar bodies.
