Heritability | Definition, Equation, & Examples | Britannica
Heritability, amount of phenotypic (observable) variation in a population that is attributable to individual genetic differences. Heritability is applied in behavior genetics and quantitative genetics, where heritability estimates can be calculated using statistical methods.
What is heritability? - MedlinePlus
Heritability is a measure of how well differences in people’s genes account for differences in their traits. Traits can include characteristics such as height, eye color, and intelligence, as well as disorders like schizophrenia and autism spectrum disorder.
Estimating Trait Heritability | Learn Science at Scitable - Nature
Heritability is a concept that summarizes how much of the variation in a trait is due to variation in genetic factors. Often, this term is used in reference to the resemblance between parents and...
2019年12月12日 · The heritability reflects the relative weight of the genetic variance component in the phenotypic variance of a specific population and is based on observations that were taken on a specific moment in time.

2024年9月26日 · Heritability estimates the relative contribution of genetic factors to the phenotypic variability observed in a population. What causes variance among organisms and among lines or varieties or strains or ecotypes?
How to estimate heritability: a guide for genetic epidemiologists
Here, we provide an overview of common methods applied in genetic epidemiology to estimate heritability, i.e. the proportion of phenotypic variation explained by genetic variation.
Heritability Definition & Meaning - Merriam-Webster
: the quality or state of being heritable. : the proportion of observed variation in a particular trait (such as height) that can be attributed to inherited genetic factors in contrast to environmental …
Heritability - SpringerLink
2024年1月31日 · Heritability is a fundamental metric in genetics and most branches of evolutionary biology. It estimates the proportion of variance in a particular trait within a population attributable to genetic differences. Typically expressed as a percentage, it illuminates the genetic underpinnings of traits and their inheritance mechanisms.
Heritability - SpringerLink
2021年1月1日 · Heritability is the statistical metric that estimates the relative influence of genetic variation (measured as genetic variance) on phenotypic variation (phenotypic variance), relative to the influence of environmental differences (environmental variance).
