"WebThe human body uses both meiosis and mitosis as methods of cell division. A single cell splits into two identical daughter cells during the process of mitosis, each of which has the same number of chromosomes as the parent cell. It takes place in somatic cells, which are the body's non-reproductive cells, and is in charge of growth and repair. " - How does meiosis provide genetic variation

WebAug 21, 2024 · Sexual Reproduction: Sexual reproduction promotes genetic variation by producing different gene combinations. Meiosis is the process by which sex cells or gametes are created. Genetic variation occurs as … WebIn sexual reproduction, chromosomes can sometimes swap sections during the process of meiosis (cell division), thereby creating new genetic combinations and thus more genetic variation. Although DNA replication is tightly regulated and remarkably accurate, errors do occur and result in mutations, which are also a source of genetic variation.
