Vedclass · Answer

(B) In a dihybrid cross,the inheritance of two traits is independent of each other according to the Law of Independent Assortment.For the seed shape trait,the cross is between round $(RR)$ and wrinkled $(rr)$.The $F_1$ generation is heterozygous round $(Rr)$.Selfing the $F_1$ generation $(Rr 	imes Rr)$ results in an $F_2$ phenotypic ratio of $3$ round : $1$ wrinkled.Therefore,the segregation ratio for the seed shape trait is $3:1$.

In a dihybrid cross between a true-breeding round yellow-seeded and a true-breeding wrinkled green-seeded pea plant,the ratio of segregation of round and wrinkled seed traits in $F_2$ is:
