WebOct 13, 2024 · Gene–environment interaction (or genotype–environment interaction or GxE or G×E) is when two different genotypes respond to environmental variation in different ways. A norm of reaction is a graph that shows the relationship between genes and environmental factors when phenotypic differences are continuous. WebRather, epistasis occurs in all of the following scenarios: Whenever two or more loci interact to create new phenotypes. Whenever an allele at one locus masks the effects of alleles at one or more ...
