E) penetrance.

Question

Quizplus · Accepted Answer

Epistasis is defined as the phenomenon where one gene masks the expression of one or more other genes, resulting in the phenotype being determined by the interaction of multiple genes. Epigenesis refers to the process of development where complex structures and functions arise from simpler ones, and is not related to gene interaction. Dominance and incomplete dominance both refer to situations where one allele is expressed over another, but do not necessarily involve multiple genes. Penetrance refers to the proportion of individuals with a certain genotype who exhibit the corresponding phenotype, and is not related to gene interaction.
