Heritability refers to the proportion of variance in a trait (such as IQ) that is attributable to genetic influences. It is usually expressed as a proportion between 0 and 1, with higher values indicating greater genetic influence. The term "concordance" is used in genetics to refer to the degree of similarity between pairs of individuals with respect to a trait or disorder. The "eugenics index" is not a recognized term in genetics, and the "correlation coefficient" is a statistical measure of the strength and direction of a relationship between two variables.
