Darwin viewed the ornamentation of females as an indirect consequence sexual selection on males and transmission male phenotypes to via 'laws inheritance'. Although a number studies have supported this view by demonstrating substantial between-sex genetic covariance for ornament expression, majority work has focused avian plumage. Moreover, few considered basis ornaments from multivariate perspective, which may be crucial understanding evolution sex differences in general, complex particular. Here, we provide multivariate, quantitative-genetic analysis sexually dimorphic that figured prominently selection: brightly coloured dewlap Anolis lizards. Using data paternal half-sibling breeding experiment brown anoles (Anolis sagrei), show multiple aspects size colour exhibit significant heritability variance-covariance structure (G) is broadly similar (Gm ) (Gf ). Whereas monomorphic dewlap, such hue, correlations (rmf ), features, area brightness, reduced rmf values do not differ zero. modified random skewers analysis, matrix (B) should strongly constrain independent responses antagonistic selection. Our microevolutionary broad agreement with macroevolutionary perspectives indicating considerable scope coloration females.
