heritability
a measure of the degree to which the total phenotype variance is the result of genetic differences and thus can be influenced by selection

Heritability
H#178;. The proportion of total phenotypic variance at the population level that is contributed by genetic variance (also called heritability in the broad sense).

Heritability
One can sort out the relative contribution of genetic and environmental factors by comparing the range of a trait in the offspring compared with the average value of that trait in their parents.

heritability (in the narrow sense)A measure of the extent to which genes inherited from parents determine phenotypes; defined as the ratio of the additive genetic variance to total phenotypic variance; also called realized heritability.

Heritability
Variability in polygenic traits can result from genetics and also from the environment. A measure of the relative contribution of genetics is called heritability.

Heritability
: The proportion of the total phenotypic variance that is attributable to hereditary variance (h2= genetic variance / total phenotypic variance). A high h2 does not mean that the trait cannot be influenced by environment.

For example, biological theories of phobias look at a heritability. Davison, Neale and Kring (2004) state that blood, injury and injection phobias run in families; ...

Genomic imprinting (which is "epigenetic") constitutes heritability that is not coded in DNA. Evolution is prevalent also in viruses, although these are not considered to be organisms. The genetic material in viruses may consist of DNA or RNA.
