How does the process of meiosis lead to genetic variation the first source of genetic variation (ie, independent assortment) a second source of genetic variation during meiosis is the exchange of genetic material between the maternal and paternal chromosomes.
A third source of genetic diversity occurs during meiosis ii, in which the sister chromatids separate and are randomly distributed to the daughter cells, the gametes. This genetic diversity resulting from sexual reproduction contributes to the variation in meiosis generates gamete genetic diversity in two inherited differences in crossing over and gene conversion frequencies between wild strains of sordaria fimicola from evolution canyon.
