The heritability of a trait
WebHeritability is a measure of how well differences in people’s genes account for differences in their traits. Traits can include characteristics such as height, eye color, and intelligence, … WebHeritability ( H) is a value that expresses the degree of this correspondence. Specifically, H is the percentage of the phenotypic variance that is attributable to differences among individuals in genotypic value. This can be seen in the equation below. When there is no genetic variance, then the numerator in this equation is 0 and H = 0.
