In the pictorial table shown below, F-2 generation genotypes are shown whose parents are RrYy genotypes .( Round Yellow ). The new combination of F2 generation is the result of
combination of alleles and independent assortment during gamete formation
The new combination of F2 generation is the result of separation of alleles and independent assortment during gamete formation & fertilization.This is explained by law of independent assortment which states that when genes are inherited, they are inherited independent of each other. This leads to formation of new combinations and not always the same as the parental characteristics.
