a) Use Hamilton's Rule to show how Kin Selection can
support the evolution of cooperation in this system. Show
the math. (4
b) Assume that the average relatedness among male turkeys in
displaying pairs was instead r = 0.10. Could kin selection
still explain the cooperative display behavior (show math)?
In this case, what alternative explanation could you give for
the behavior? (4 pts)
