Chapter 4, Problem 4RQ
Summary Introduction
To list: The type of cell junctions and their functions.
Introduction: The attachment point between the cells in a tissue that binds the cells firmly together, ceases the leakage, and serves as the communication channels is known as cell junction. Cell junction holds the cells together inside a tissue and allows the cellular communication inside or outside the tissue.

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)?
