WebNov 20, 2024 · There are two types of cell division: mitosis and meiosis. Mitosis is the process by which body cells divide and create copies of themselves for growth and repair. In meiosis, the new cells have half the genetic material of the parent cell and is the process by which egg and sperm cells are formed. Difference Between Mitosis and Meiosis WebApr 12, 2024 · The masking theory states that genes expressed in haploid stage will be under more efficient selection. In contrast, selection will be less efficient in genes expressed in diploid stage, where the fitness effects of recessive deleterious or beneficial mutations can be hidden from selection in heterozygous form. This difference can influence several …
