Question

part c 

A species of bird shows variation in wing-length (measured from the bird's shoulder to the tip of the longest feather). You measure wing-length in a population of these birds and find a mean wing-length of 13 cm. You calculate a heritability of wing-length to be 1. That summer, there is a severe drought. Many of the birds die and only a few survive to reproduce. The surviving birds have a mean wing-length of 16 cm. a) What is the predicted mean wing-length of the offspring of the surviving birds? [ [ Select ] b) What type of selection was acting on wing-length in these birds? I Select ] c) Five years later, you go back and measure wing-length in this bird population again.
