The heritability of body size is 0.2 in Atlantic silversides.What would happen to figure 11.21 if this heritability was 0.8?

Question

Quizplus · Accepted Answer

A higher heritability of body size means that genetic variation plays a larger role in determining body size. Therefore, if the heritability of body size in Atlantic silversides was 0.8 instead of 0.2, the changes in average size would occur more rapidly as genetic variation would have a greater impact on body size in subsequent generations.
