Solution
The correct option is B Law of segregation According to the law of seggregation alleles of a trait that remain together in an individual do not mix but rather keep their identity intact. They separate during gamete formation and get randomly distributed only to get paired again in the offspring’s as per the principle of probability. This results in a phenotypic trait in the 3:1 ratio in the F2 generation i.e when a heterozygous plant is crosssed. So, the correct answer is 'Law of segregation'.
