Question

Find examples where the four daughter cells from meiosis are equal in size and where they are found unequal in size.

Answer 1

In an average mammal (i.e., human being), the four daughter cells that result from meiosis are of comparable size during the creation of male gametes, or spermatozoa. However, in a typical mammal (i.e., human being), during the production of the female gamete (i.e., ovum), the four daughter cells are not of similar size.

Answer 2

• Gametes are formed by meiosis.
• In spermatogenesis, all four daughter cells formed by the division of the mother cell are equal. They produce sperm through spermatogenesis.
• The four daughter cells formed in spermatogenesis are equal in size. In oogenesis, the daughter cells formed from the mother cell differ in size.
• As a result of ovulation, an egg and polar cells are formed. Polar cells are small in size. As a result of megasporogenesis (meiosis) in the ovule of plants, four cells are formed from the megaspore. In these cells, the basal cell is different from other cells. It forms the embryo sac through growth and division.
• In plants, small spores, or pollen grains, are formed by microsporangia. These are similar in size.
