Question

Quizplus · Accepted Answer

Heritability refers to the extent to which differences in a trait within a population are explained by genetic differences. A heritability of 50% means that 50% of the variability in intelligence in a population of individuals is due to variations in genetic inheritance, while the other 50% is attributed to environmental factors. It does not mean that 50% of a person's intelligence is solely due to genetic inheritance, or that it can explain differences in intelligence between different ethnic groups.
