If both genes in a pair of genes affect the phenotype, then the alleles may be considered __________.

Question

Quizplus · Accepted Answer

When both alleles in a pair of genes affect the phenotype, they are considered codominant. This means that both alleles are expressed equally in the phenotype. In incomplete dominance, one allele is partially dominant over the other, resulting in an intermediate phenotype. "Phenotypical" and "genotypical" are not terms used to describe the relationship between alleles in a pair of genes.
