Detailed explanation-1: -In scientific terms, heritability is a statistical concept (represented as h²) that describes how much of the variation in a given trait can be attributed to genetic variation.
Detailed explanation-2: -(HAYR-ih-tuh-BIH-lih-tee) The proportion of variation in a population trait that can be attributed to inherited genetic factors. Heritability estimates range from 0 to 1 and are often expressed as a percentage. A number close to 1 may be indicative of a highly heritable trait within a population.
Detailed explanation-3: -To conclude, groups that differ in mean ability can differ in heritability of the test scores because tests differ in measurement precision over the ability range, even if the heritability of the trait is equal across groups.
Detailed explanation-4: -Heritability measures how important genetics is to a trait. A high heritability, close to 1, indicates that genetics explain a lot of the variation in a trait between different people; a low heritability, near zero, indicates that most of the variation is not genetic.
Detailed explanation-5: -Heritability is a population parameter and, therefore, it depends on population-specific factors, such as allele frequencies, the effects of gene variants, and variation due to environmental factors. It does not necessarily predict the value of heritability in other populations (or other species).
