Why is it incorrect to say that 5o percent heritability of intelligence means that the cause of your intelligence is 50 percent genetic and 50 percent environmental?

Answer with explanation:

It is incorrect to say that 50% heritability of intelligence means that the cause of the intelligence is 50% genetic and 50% environmental.

Because heritability accounts for variations among people, not in specific individuals which means that the cause is not 50% environmental or 50% genetic but rather based on variations among individuals
