a P and Q become associated, with μP = 0.0002 and \({\mu }_{\overline{P}}={\mu }_{Q}={\mu }_{\overline{Q}}=.0001\). b \(\overline{P}\) becomes associated with \(\overline{Q}\), while P is not strongly associated to either, with \({\gamma }_{\overline{P}}=.0001\) and μ = 0.001. In both panels, α0 = 0.01, α1 = 1 and β = 0.001, with initial frequencies \({x}_{\overline{P}}=.1\), \({x}_{\overline{Q}}=.1\) and x0 = 0.8.
