Growth factor gene IGF1 is associated with bill size in the black-bellied seedcracker Pyrenestes ostrinus
Pyrenestes finches have a bill size polymorphism thought to be maintained by disruptive selection. Here, the authors identify a single candidate region, including insulin-like growth factor 1, differentiating small and large bill size morphs and a wider region differentiating the mega-billed morph.
