  bibo_abstract:
  - The evolution of sexual dimorphism (the difference in average trait values between
    females and males, SD), is often thought to be constrained by shared genetic architecture
    between the sexes. Indeed, it is commonly expected that SD should negatively correlate
    with the intersex correlation (the genetic correlation between effects of segregating
    variants in females and males, r fm), either because (1) traits with ancestrally
    low r fm are less constrained in their ability to respond to sex-specific selection
    and thus evolve to be more dimorphic, or because (2) sex-specific selection, driving
    sexual dimorphism evolution, also acts to reduce r fm. Despite the intuitive appeal
    and prominence of these ideas, their generality and the conditions in which they
    hold remain unclear. Here, we develop models incorporating sex-specific stabilizing
    selection, mutation and genetic drift to examine the relationship between r fm
    and SD. We show that the two commonly-discussed mechanisms with the potential
    to generate a negative correlation between SD and r fm could just as easily generate
    a positive association, since the standard line of reasoning hinges on a hidden
    assumption that sex-specific adaptation more frequently favors increased dimorphism
    than reduced dimorphism. Our results provide, to our knowledge, the first mechanistic
    framework for understanding the conditions under which a correlation between r
    fm and SD may arise and offer a compelling explanation for inconsistent empirical
    evidence. We also make the intriguing observation that—even when selection between
    the two sexes is identical—drift generates nonzero SD. We quantify this effect
    and discuss its significance.@eng
