How do we measure genetic variation
WebHeritability is a fundamental concept in genetics. It is a parameter that summarizes how much of the variation in trait values in a population is due to variation in genetic factors. WebHeritability 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.In scientific terms, heritability is a statistical concept (represented as h²) that describes how much of the …
