A condition in which one gene pair masks the expression of a nonallelic gene pair is called ________.
A) codominance
B) epistasis
C) dominance
D) recessiveness
E) additive alleles

Question

Quizplus · Accepted Answer

Epistasis is a genetic interaction where one gene or allele affects or masks the expression of another gene or allele, which is nonallelic (not on the same chromosome). This is different from dominance, which is the relationship between two alleles of the same gene, and codominance, where both alleles are expressed equally. Recessiveness refers to the expression of one allele being suppressed or masked by a dominant allele. Additive alleles contribute equally to a phenotype.
