Difference between ${\mathit{\gamma }}_g$ and ${\widehat{\mathit{\gamma }}}_G$. For the scenario with different values of the (true) difference between ${\mathit{\gamma }}_g$ and ${\mathit{\gamma }}_G$, and for different values of relatedness r between group mates, and R ₀ = 1.2. (${\mathit{\gamma }}_g={\mathit{\phi }}_f=1)$
