Meiosis produces four genetically non-identical daughter cells, which increases genetic variation among gametes (and, therefore, genetic diversity in the population). Cite This Article

WebGenetic variation is introduced during meiosis - a form of cellular division.This process produces genetically different sex cells, called gametes, for sexual reproduction.
