WebSep 4, 2024 · A gamete produced by a female is called an egg, and the process that produces a mature egg is called oogenesis. Just one egg is produced from the four haploid cells that result from meiosis. The single egg is a very large cell, as you can see from the human egg also shown in Figure 7.5. 5. WebMitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

WebMeiosis is a process where germ cells divide to produce gametes, such as sperm and egg cells.
