alleryA heritability of 0.6 for a trait refers to:
Aone person's inherited share
Bvariation across a population
Cchance of passing it on
Dthe parents' contribution
Answer & Solution
Correct answer: B. variation across a population
1. Heritability is a population statistic about differences between people.
2. It does not say that 60% of one person's trait is inherited from the parents.
3. So 0.6 describes variation across a population, not one person.
