Abstract excerpt
Speciation with gene flow may require adaptive divergence of multiple traits to generate strong ecologically based reproductive isolation. Extensive negative pleiotropy or physical linkage of genes in the wrong phase affecting these diverging traits may therefore hinder speciation, while genetic independence or "modularity" among phenotypic traits may reduce constraints and facilitate divergence. Here, we test...
