Heritability does not indicate what proportion of a trait is determined by genes and what proportion is determined by environment. So, a heritability of 0. Knowing the heritability of a trait does not provide information about which genes or environmental influences are involved, or how important they are in determining the trait.

Heritable is not the same as familial. A trait is described as familial if it is shared by members of a family. Traits can appear in families for many reasons in addition to genetics, such as similarities in lifestyle and environment. For example, the language that is spoken tends to be shared in families, but it has no genetic contribution and so is not heritable. Heritability does not give any information about how easy or difficult it is to change a trait.

For example, hair color is a trait with high heritability, but it is very easy to change with dye. If heritability provides such limited information, why do researchers study it? Heritability is of particular interest in understanding traits that are very complex with many contributing factors. Moore DS, Shenk D. For human behavior, almost all estimates of heritability are in the moderate range of. The quantity 1. Environmentability has an analogous interpretation to heritability.

It is the proportion of phenotypic variance attributable to environmental variance or the extent to which individual differences in the environment contribute to individual differences in behavior. If the heritability of most human behaviors is in the range of.
