Question

Why does ova production result in one egg and three polar bodies?

a. This allows the egg to receive most of the cytoplasm.
b. This reduces egg size by distributing most of the cytoplasm to the polar bodies.
c. This allows the egg to receive all of the chromosomes.
d. It is not known why this process occurs.

Answer 1

Oogenesis results in one egg and three polar bodies. The egg receives most of the cytoplasm, while the polar bodies degrade.

Step-by-step explanation:

Oogenesis, the process of egg production in females, results in the formation of one mature egg and three polar bodies. The polar bodies, which contain very little cytoplasm, eventually degrade and disappear. The reason for this unequal cell division is to ensure that the egg receives most of the cytoplasm, nutrients, and organelles, as it needs to provide all the necessary materials for the developing embryo. Therefore, option a. This allows the egg to receive most of the cytoplasm, is the correct answer.
