During oogenesis, which cell receives most of the cytoplasm, with polar bodies degenerating?

Explanation:
During oogenesis, the division of cytoplasm is unequal. The egg (oocyte) retains most of the cytoplasm and organelles so it has the resources needed to support the embryo after fertilization. The smaller cells produced, called polar bodies, receive only a little cytoplasm and are typically wasted, degenerating rather than contributing to offspring. So, the statement that describes one cell receiving most of the cytoplasm while polar bodies degenerate is the accurate picture. The other ideas imply equal or random cytoplasm distribution or two cells sharing the majority, which isn’t how oogenesis works.
