Detailed explanation-1: -So, although meiosis produces four cells in total, only one of these is an egg cell. Therefore, at the end of oogenesis, from each primary oocyte that enters meiosis, the number of egg cells produced is one egg.

Detailed explanation-2: -A single cell divides to make two cells and these two cells then divide to make four cells, and so on. We call this process “cell division” and “cell reproduction, ” because new cells are formed when old cells divide. The ability of cells to divide is unique for living organisms.

Detailed explanation-3: -Stages of meiosis. Meiosis contains two separate cell divisions, meaning that one parent cell can produce four gametes (eggs in females, sperm in males). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

Detailed explanation-4: -The eggs of most animals are giant single cells, containing stockpiles of all the materials needed for initial development of the embryo through to the stage at which the new individual can begin feeding. Before the feeding stage, the giant cell cleaves into many smaller cells, but no net growth occurs.
