Explanation:
Detailed explanation-1: -A polar body is a small haploid cell that is formed at the same time as an egg cell during oogenesis, but generally does not have the ability to be fertilized. It is named from its polar position in the egg.
Detailed explanation-2: -During fertilization, the acrosome’s secretion helps the sperm to enter into the cytoplasm of the ovum. This induces the completion of the second meiotic division of the secondary oocyte. The second meiotic division results in the formation of a second polar body and a haploid ovum.
