You are studying the effect of directional selection on body height in three populations (a, b, and c) below. (a) What is the selection differential? Show your calculation.
(b) Which population has the highest narrow sense heritability for height? Explain your answer.
(c) If you examined the offspring in the next generation in each population, which population would have the highest mean height? Why?
