In males, 4 sperms are produced from 1 progenitor cell.
In females, 1 ovum is produced from 1 progenitor cell.
This happens because the process of gametogenesis is a meiosis process in which at the end 4 haploid cells are produced. In male this happens normally and 4 sperms are formed while in female 3 of the 4 divided cells becomes polar bodies and that leaves human female with 1 ovum from every progenitor cell.

1. In walruses, males defend a large harem of females and will fight with other males to maintain dominance and access to their harem. However, there are some males that are smaller and will mimic female walruses, hiding among them and occasionally mating with them. Researchers observed a walrus population and found that there were 75 offspring produced. Of those, the female mimic male was the father of 25, the dominant males was the father of 50 and each of...

6. In goats, beards are produced by an autosomal allele that is expressed differently in males and females: The bearded allele (Bº) is dominant over the beardless allele (B") in males, but recessive in females. Therefore, males only need one copy of the bearded allele to be bearded, but females need two copies of the bearded allele to be bearded. Another independently assorting autosomal allele determines coat color: black coat (L) is completely dominant over white coat (1). For each...

5. In Drosophila, males from a true-breeding stock with raspberry-colored eyes were mated to females from a true-breeding stock with sable-colored bodies. In the F1 generation, all the females had wild-type eye and body color, while all the males had wild-type eye color but sable-colored bodies. When F1 males and females were mated to each other, the F2 was composed of: 216 females with wild-type eyes and wild-type bodies 223 females with wild-type eyes and sable bodies 191 males with...
