WebApr 9, 2024 · Complementary gene action and genetic epistasis in the context of pathways. Considering that biological processes are controlled by multiple genes acting together, several genetic principles make more sense. First, it becomes clear how mutations in different genes can produce the same phenotypic effects. Since multiple … WebIn epistasis, the interaction between genes is antagonistic, such that one gene masks or interferes with the expression of another. “Epistasis” is a word composed of Greek roots meaning “standing upon.” The alleles that are being masked or silenced are said to be hypostatic to the epistatic alleles that are doing the masking.

WebJun 8, 2024 · Additive and nonadditive genetic patterns explain the quantitative genetics of organisms. Additive genetic patterns arise due to the additive effects of both alleles in a gene in measurable varying amounts. In contrast, nonadditive genetic patterns explain the effect of a single allele on the phenotype through dominance or epistasis.
