Question

Quizplus · Accepted Answer

Heritability estimates are computed by comparing IQ correlations between twins and other relatives. This method allows researchers to estimate the proportion of individual differences in IQ that can be attributed to genetic factors rather than environmental factors. By comparing correlations between different types of relatives, researchers can also estimate the extent to which genetic and environmental factors interact to influence intelligence.
