Species-specific description: Lamichhaney et al. (2016): "The ruff is a Palearctic wader with a spectacular lekking behavior where highly ornamented males compete for females . . . . This bird has one of the most remarkable mating systems in the animal kingdom, comprising three different male morphs (independents, satellites and faeders) that differ in behavior, plumage color and body size."

Molecular basis: Lamichhaney et al. (2016) "confirmed complete association between the Satellite allele and . . . four missense mutations, whereas the faeder was heterozygous for the variant encoding p.His207Arg and three other missense mutations . . . . The p.His207Arg substitution most likely has functional consequences because the same variant is associated with light color in the red-footed booby [see OMIA 000374-57662] . . . . We propose that the MC1R allele on Satellite chromosomes, possibly together with altered metabolism of sex hormones, underlies the white color of ornamental feathers in satellites. To be causal, this allele must have a dominant effect, as satellites are always heterozygous."
