GENERAL HISTOLOGY

Detailed explanation-1: -A polar body is the byproduct of an oocyte meiotic division. It is the small cell that normally apoptoses, and in textbook figures, it usually just disappears.

Detailed explanation-2: -Therefore, female meiosis produces one haploid mature egg, alongside two polar bodies (or sometimes three polar bodies if the first polar body further divides). This is in contrast to meiosis in the testes in which one diploid spermatogonium produces four haploid mature sperms [Clermont, 1972].

Detailed explanation-3: -Polar bodies remove one-half of the diploid chromosome set produced by meiotic division in the egg. So, the secondary oocyte and first polar body are haploid.

Detailed explanation-4: -These cells start division and enter into prophase-I of the meiotic division and get temporarily arrested at that stage, called primary oocytes. This eventually undergoes unequal division resulting in the formation of a large haploid secondary oocyte and a tiny first polar body.
