Detailed explanation-1: -Meiosis also allows genetic variation through a process of gene shuffling while the cells are dividing.
Detailed explanation-2: -Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
Detailed explanation-3: -Gametes, or reproductive cells, are produced in a special kind of cell division called meiosis. During this process the normal number of the cell’s chromosomes is reduced by half. Each gamete ends up with a copy of one chromosome from each pair.
Detailed explanation-4: -Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
