The Law of independent assortment states that during gamete formation, two genes assort independently and are arranged randomly in the progeny during fertilisation producing parental type and the recombinant types. A true-breeding homozygous pea plant with green pods and axial flowers as dominant characters is crossed with a recessive homozygous Pea plant with yellow pods and terminal flowers. In the F 1 generation, only the dominant allele will be expressed and all the progeny will be heterozygous for both genes. Upon crossing the F 1 progeny new phenotypes were observed in the F 2 generation. Phenotype ratio of F 2 generation — Green pods and axial flowers: Green pods and terminal flowers: Yellow pods and axial flowers: Yellow pods and terminal flowers are 9:3:3:1. Green pods and terminal flowers and Yellow pods and axial flowers phenotypes were not present in either of the parents, but it appeared in the F 2 generation shows that genes were assorted independently.
