Juan is reading an academic article claiming that the heritability of intelligence is approximately 63%. He interprets this as meaning that in explaining the average person’s intelligence, roughly 63% of that persons intelligence is inherited or caused by their genes. It is Juan’s interpretation correct? Why or why not?
What will be an ideal response?
No, heritability estimates indicate the percentage of population variance on a trait that is explained by genes, not an individual’s score on that trait.
