Meeting Abstract 94.4  Monday, Jan. 6 14:15  Testosterone pleiotropically regulates sexual dimorphism in multiple traits COX, C. L.*; HANNINEN, A. F.; REEDY, A. M.; COX, R. M.; The University of Virginia; The University of Virginia; The University of Virginia; The University of Virginia clcox@virginia.edu Sexual dimorphism is predicted to evolve slowly as genetic correlations are gradually eroded. […]

Meeting Abstract 94.2  Monday, Jan. 6 13:45  Sexually dimorphic learning in a butterfly: learning biases, mate choice, and sexually dimorphic ornamentation WESTERMAN, E.L.*; MONTEIRO, M.; University of Chicago; National University of Singapore ewesterman@uchicago.edu Mate preferences are learned in a wide variety of taxa with sexually dimorphic ornamentation. However, it is unclear what role sexual dimorphism in mate […]

Meeting Abstract 94.1  Monday, Jan. 6 13:30  Effects of domestication on sexual dichromatism in the island canary KOCH, R.E.*; HILL, G.E.; Auburn University; Auburn University rek0005@auburn.edu In many songbird species, males exhibit flashier and more colorful plumage than females. This sexual dichromatism is commonly accepted to arise through sexual selection, though research on the topic is heavily […]

Meeting Abstract 94.3  Monday, Jan. 6 14:00  Developmental erosion of between-sex genetic correlations in a sexually dimorphic lizard COX, R.M.*; MCGLOTHLIN, J.W.; University of Virginia; Virginia Tech rmc3u@virginia.edu Selection often favors dramatically different phenotypes in males and females, but quantitative-genetic theory predicts that the subsequent evolution of sexual dimorphism is potentially constrained by between-sex genetic correlations for […]
