Which genetic phenomenon describes the inheritance pattern where heterozygous individuals display a distinct intermediate phenotype blending the traits of both homozygous parents?

💡 Solution & Explanation

Incomplete dominance occurs when neither allele is completely dominant over the other, resulting in a hybrid phenotype that is an intermediate blend, such as pink flowers produced by crossing red and white snapdragons. Codominance involves the simultaneous expression of both alleles without blending, as seen in the AB blood group system. Complete dominance masks the recessive trait entirely in heterozygous individuals. Epistasis occurs when one gene locus masks or modifies the phenotypic expression of an independent gene locus.
