i cant believe that a computer doesnt even know the answer of such asimple question
oogenisis
mammary glands
after oogenisis the polar bodies disintegrate
It is the formation of an ovum. The primary oocyte turns to an ovum undergoing meiosis.
spermatogenesis produces 4 sperm cells and oogenisis produces one ovum. Both have 23 chromosomes each
The cytoplasm divides unequally during the production of ova (Oogenisis) This is because out of the four daughter cells created during meiosis, only one is needed to produce a single ovum, whearas in Spermatogenisis all four evolve to become sperm; thus the cytoplasm is divided equally.
