WebDuring mitosis, the cell division part of the cell cycle, a single parent cell’s replicated genetic material—called chromosomes—divides to produce two new, genetically-identical daughter cells. In the cell cycle, the cell’s DNA is replicated in interphase, the phase that precedes mitosis. Mitosis alternates with interphase to make up ... Web7 Meiosis At some point in the evolutionary history of life on earth, sex-ual reproduction evolved as a mechanism to increase genetic diversity in a species, a good way to ensure survival of the species in an ever-changing environment. Sexual reproduc-tion is the fusion of chromosomes from one individual with the chromosomes of another individual.

WebMeiosis. The process of meiosis preserves genetic continuity for future offspring by ensuring that two sexually reproducing organisms produce offspring that have the same number of chromosomes as the parents. This is important for several reasons. First, it ensures that each offspring has all the genes that it needs in order to survive.

WebApr 11, 2024 · Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm).
