Because questions build on the results of preceding questions, you are encouraged to write out your calculations and results as you work through this assignment.
Suppose that you are interested in the recent introduction of a non-native avian predator, a falcon, and how it has influenced the evolution of flight in one of its prey species, the song sparrow (Melospiza melodia). Just prior to the introduction of the falcon, the mean wing length of sparrows was 10 cm. Following one season of predation by falcons, the mean wing length in the surviving sparrows was 8 cm.
If the mean wing length of the offspring of these surviving sparrows is 8.8 cm, what is the narrow-sense heritability h^2 for wing length?
