Why is meiosis necessary in organisms that reproduce sexually?
Meiosis is the process of cell division that creates gametes (sex cells) that are required for sexual reproduction. In meiosis, a cell divides twice to produce four new cells. Each new cell has half the number of chromosomes as the original cell. It is necessary because it helps all sexually reproducing organisms pass down half their genes to their offspring. Sexual reproduction also contributes to genetic diversity, which helps species evolve and adapt over time.…
