Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and matura…
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:

Step 1

Introduction : 

A single cell divides twice to form four cells during the meiosis process. The amount of genetic data generated from parental chromosomes is reduced by half. Meiosis I and Meiosis II are the two stages of meiosis.

Meiosis plays a crucial role in ensuring that all organisms created through sexual reproduction have the appropriate amount of chromosomes. Recombination during meiosis is crucial for bringing about genetic diversity. It improves the likelihood of survival.
