Unformatted text preview: t effects alone, e.g., epistasis Environment The environment can shape a phenotype: different environments cause different phenotypes to develop Vz =[VA +VD +VI]+VE For now we have two sources of phenotypic variance. Genetic and environment. Genetics can be subdivided into three components. The additive component is like looking at the effect of each allele in isolation. We don’t know the worth of an allele in isolation. We do this by seeing on average the on average effect of that allele. Is this evenly divided between dominant and recessive alleles, or do the contributions of the alleles differ depending on dominance? The dominant effe...
