NEET PG DENTAL EXAM

Detailed explanation-1: -Polar bodies serve to eliminate one half of the diploid chromosome set produced by meiotic division in the egg, leaving behind a haploid cell. To produce the polar bodies, the cell must divide asymmetrically, which is fueled by furrowing (formation of a trench) near a particular point on the cell membrane.

Detailed explanation-2: -Polar bodies are very small and haploid cells that can not undergo fertilization. All the cytoplasm is segregated into one daughter cell that becomes the egg or ovum. The other polar bodies with a small amount of cytoplasm will usually die and disintegrate by apoptosis.

Detailed explanation-3: -Spermatogenesis produces four haploid sperm cells from each diploid precursor cell, while oogenesis produces one egg cell and two or more polar bodies.
