Detailed explanation-1: -Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
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: -The dividing of the DNA ensures that both the “old” cell (parent cell) and the “new” cells (daughter cells) have the same genetic makeup and both will be diploid, or containing the same number of chromosomes as the parent cell.
Detailed explanation-4: -When a cell divides, the outer membrane increasingly pinches inward until the new cells that are forming separate from each other. This process typically produces two new (daughter) cells from one (parent) cell. During cell division, the contents of the parent cell are copied and divided between the two daughter cells.
Detailed explanation-5: -Each daughter cell has half the number of chromosomes as compared to their parents (one copy of each chromosome). The resulting cells from meiosis are not genetically identical because of the recombination of genes that occurred during prophase 1. Sex cells in humans are produced by meiosis.
