Explanation

Independent Assortment of Chromosomes The paternal and maternal chromosomes of each homologous pairs segregates during anaphase-I independently of the other chromosomes. Anaphase-I is the cytological event that corresponds to Mendel’s law of independent assortment. Although the paternal and maternal chromosomes of a homologous pair have the genes for the same traits, either chromosome of a pair may carry different alleles of the same genes. Therefore, independent assortment of homologous chromosomes in anaphase-I introduces genetic variability
