Vedclass · Answer

(A) Complementary genes are two independent pairs of genes that interact to produce a single trait,where each gene is required for the expression of the other.In the $F_2$ generation of a dihybrid cross involving complementary genes,the phenotypic ratio is modified from the standard $9 : 3 : 3 : 1$ to $9 : 7$.This occurs because the presence of at least one dominant allele at both loci $(A-B-)$ results in one phenotype (ratio $9$),while any other combination (where one or both genes are homozygous recessive) results in the alternative phenotype (ratio $3+3+1 = 7$).

The phenotypic ratio of complementary genes is ................
