WebAs a result of the independent assortment, the meiosis process causes genetic variation. As a result, there are four primary forms of meiosis that result in genetic variation. During meiosis, it involves 1) mutation, 2) random fertilization, 3) random mating among organisms, and 4) crossing over between homologous chromosomes with chromatids. WebJul 7, 2024 · Advertisement We have seen that meiosis creates variation three ways: crossing over, mutations caused during crossing over, and independent assortment.
