Modified dihybrid phenotypic ratios in epistasis:
(A) Dominant Epistasis -> (II) 12:3:1: When a dominant allele of one gene masks the expression of both alleles of another gene (e.g., fruit color in summer squash).
(B) Inhibitory Gene Action -> (I) 13:3: When a dominant inhibitor gene suppresses the expression of a dominant allele of another gene (e.g., feather color in fowl, grain color in rice).
(C) Duplicate Epistasis (Duplicate Dominant) -> (III) 15:1: When either of two independent dominant genes produces the phenotype (e.g., shepherd's purse fruit shape, awned vs awnless in rice).
(D) Complementary Gene Action (Duplicate Recessive) -> (IV) 9:7: When dominant alleles of both genes must be present together to produce the phenotype (e.g., flower color in sweet pea).
