Figure 7

Evolution of multiple preferences for condition dependent male traits. This figure shows the parameter space, in terms of costs of competition (γ) and strength of female preference (α), where a single preference for a condition dependent trait fixes (gray), both preferences fix (white), and both preferences are lost (black). Top row displays results for successive preference introduction, the bottom row shows simultaneous preference introduction. The left column displays results for simulations where the condition allele evolved along with female preference and the right column shows results from simulations where female preference was introduced into a population at mutation selection balance for a high condition allele.
