Genetic heritability
WebA heritability of 60% says nothing about the contribution of genes to an individual's risk of a phenotype. Also, since the heritability is defined as the ratio V G /(V G + V E), as the environmental variance increases, the genetic component (heritability) decreases. Put another way, if the genetic homogeneity of a population increases, the ... WebHeritability measures the fraction of phenotype variability that can be attributed to genetic variation. This is not the same as saying that this fraction of an individual phenotype is …
