"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. " - The heritability of a trait

WebJun 30, 2016 · Heritability is the fraction of the variation in phenotype of a trait that is accounted for by the variation in genotype. Phenotype is simply the expression of a trait, whether it be behavior, anatomy, function, or whatever. Genotype is the genetic makeup of the animal. So for example, if we are talking about the heritability of aggression in ... WebHeritability estimates can range from 0 to 1; when the estimate is higher (closer to 1), this means that genes have a larger influence on the behavior of interest, as it would be with blood type. When the estimate is lower (closer to 0), it reflects a larger impact of the environment on the behavior.

WebMar 7, 2024 · Heritability—the fraction of variability in a trait attributable to genetic variation, usually additive variation—is often used as a proxy for evolvability because it can predict how strongly a population responds to selection over the space of a generation.
