<sub>Heritability

Definition:</sub>

Heritability is a statistical measure that quantifies the proportion of phenotypic variation within a population that is due to genetic factors. It estimates the extent to which differences in observable traits or characteristics, such as height or intelligence, can be attributed to genetic variation rather than environmental influences.

<sub>Subcomponents:

1. Genetic Variation:</sub>

This measures the range of genetic differences or variations within a population. Genetic variation encompasses the presence of different alleles, gene mutations, or gene combinations that can contribute to the observed phenotypic variation.

_{2. Environmental Influence:}

This factor takes into account the impact of external factors, such as diet, education, and exposure to various external stimuli, that can also influence phenotypic variation. Environmental factors can interact with genetic factors and influence the expression of certain traits.

_Usage:

Heritability is commonly used in genetics and behavioral sciences to determine the relative contribution of genetic and environmental factors in shaping a particular trait or characteristic. It is usually expressed as a value between 0 and 1, with 0 indicating no genetic influence and 1 indicating complete genetic determination of the trait.
