Effects of mutations in pigeon Mc1r implicate an expanded plumage color patterning regulatory network
Shreyas Krishnan, Richard L. Cryberg
The paper identifies a frameshifting deletion in pigeon Mc1r linked to a recessive pigmentation trait and shows that Mc1r loss increases eumelanism without pheomelanism, suggesting Mc1r-independent pathways in birds.
