Repeatability measures the consistency of repeated trait measurements within individuals. Learn its formula, relationship with heritability, permanent environmental effects, breeding value, selection, and quantitative genetics.
Realized heritability measures heritability from the observed response to selection. Learn its formula, selection differential, additive genetic variance, breeding value, genetic gain, breeding, and evolution.
Heritability describes the proportion of phenotypic variation associated with genetic differences in a population. Learn about broad- and narrow-sense heritability, genetic variance, environmental effects, selection, breeding, and evolution.
Genetic covariance describes how genetic effects influencing two traits vary together. Learn how it relates to genetic correlation, pleiotropy, the G-matrix, selection, breeding, and evolution.
Covariance among relatives measures the similarity of relatives for a trait and helps estimate additive genetic variance, heritability, breeding values, genetic correlations, and the inheritance of complex traits.
Environmental variance describes differences in phenotypes caused by environmental and non-genetic factors. Learn how environmental conditions, G×E interactions, heritability, and quantitative genetics influence trait variation.
Genetic variance describes genetic differences among individuals that contribute to phenotypic variation. Learn about additive, dominance, and epistatic variance, heritability, genetic architecture, selection, breeding, and evolution.
Epistatic variance is the component of genetic variance caused by interactions between different genetic loci. Learn how epistasis influences complex traits, genetic architecture, heritability, breeding, natural selection, and evolution.
Dominance variance is the component of genetic variance caused by interactions between alleles at the same locus. Learn how it affects phenotypic variation, heritability, breeding, heterosis, inbreeding, and evolution.
Additive genetic variation is the heritable component of genetic variation that contributes predictably to differences among individuals and determines much of the response to natural and artificial selection.
Environmental variation refers to differences in phenotypes caused by differences in environmental conditions. Learn how nutrition, temperature, climate, development, and other factors influence traits and interact with genetic variation.
Continuous variation occurs when a trait shows a continuous range of phenotypic values. Learn how polygenic inheritance, genetic variation, environment, heritability, and quantitative genetics shape these traits.
