Question

The narrow-sense heritability of wing length in a population of
Drosophila melanogaster is 0.8. The narrow-sense heritability of head
width in the same population is 0.9. The genetic correlation between
wing length and head width is −0.86. If a geneticist selects for increased
wing length in these flies, what will happen to head width?
