Figure 5.

Relative reproductive rate ω₁ at a neutral marker locus (27) induced by overdominant selection (α₀ = β₂ = 0.8, α₂ = β₀ = 0.7, α₁ = β₁ = 1) in the absence of segregation distortion (d₁ = d₂ = 1/2). With the exception of very tight linkage between the marker locus and the target of selection (r → 0), for which ω₁ converges to the value given by (26), ω₁ remains close to unity.
