Definition

In population and behavioral genetics, gene-environment correlation occurs when genetic variance and environmental variance are correlated in a heritability analysis. This happens when there is an association between an individual’s genetic background and their environment, resulting in an association between environmental and genetic differences at a population level.

Introduction

Heritability (H 2) is a statistical parameter that estimates how much variation in a trait or phenotype within a population is due to genetic differences between individuals in that population. To arrive at an estimate, variation is encompassed in the statistical term variance. H 2 is summarized as the proportion of genetic variance (V G) (as opposed to environmental variance (V E)) that accounts for phenotypic variance (V P) (Eq. 1):
$$ {\mathrm{H}}^2=\frac{{\mathrm{V}}_{\mathrm{G}}}{{\mathrm{V}}_{\mathrm{P}}} $$
