Detailed explanation-1: -The heritability of intelligence refers to. the proportion of variation in intelligence among individuals that is attributable to genetic variation. A test that measures or predicts what it is supposed to is said to have a high degree of. validity. A test has a high degree of validity if it.
Detailed explanation-2: -Heritability is a measure of how much a trait’s variation (such as the level of your mathematical intelligence) seems to be the result of the parents’ physical characteristics, versus the effects of other factors, such as environment, exposure to stimuli, random chance, etc.
Detailed explanation-3: -Heritability is the proportion of variation among individuals that can be attributed to genes.
Detailed explanation-4: -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-5: -genetic influence explains 50 percent of the observed variation among people.
