Vedclass · Answer

(A) In a dihybrid cross,Mendel studied the inheritance of two pairs of contrasting traits simultaneously.According to the Law of Independent Assortment,the inheritance of one pair of traits is independent of the other.Therefore,for each individual trait,the $F_2$ generation follows the same phenotypic ratio as observed in a monohybrid cross.The phenotypic ratio for a monohybrid cross in the $F_2$ generation is $3:1$ (dominant to recessive).Thus,for any single pair of contrasting traits in a dihybrid cross,the ratio remains $3:1$.
