How does meiosis result in genetic variation

WebThere are several points during sexual reproduction at which genetic variation can increase. In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis. WebJul 30, 2024 · Meiosis and fertilization create genetic variation by making new combinations of gene variants (alleles). In some cases, these new combinations may make an organism more or less fit (able to survive and reproduce), thus …

WebMeiosis is a process of cell division. It is a process in which one single parent cell produces four cells with half the number of chromosomes from which the cells that they were originated from, that is the parent cell.
