the genetic basis of sexual dimorphism in birds

We narrowed our search to female hybrids between sexually dimorphic species whose males possess different types of ornamental traits (e.g., distribution of color patches; presence/absence of headwires, elongated feathers, or wattles). This maximized our chances of seeing expression of dimorphic trai ...
