Cross-species summary: Bill colour, BCO2-related

Species-specific description: Enbody et al. (2021) "report a combined field and molecular-genetic investigation of a nestling beak color polymorphism in Darwin's finches. ... we show that the polymorphism arose in the Galápagos half a million years ago through a mutation associated with regulatory change in the BCO2 gene and is shared by 14 descendant species."

See 'OMIA 002466-48883 : Beak colour, BCO2-related in Geospiza fortis' for information on history, inheritance, mapping and molecular basis.
