Likely breed origin and age ascertained from literature (Roberts, 1997; Scrivener, 2006, 2009), three-letter country code (ISO 3166-1 alpha-3).
AvianDiv Project (AD), Private Breeders (PB), Roslin Institute (RI), Olivier Hanotte (OH), Negussie Dana (ND) and José Alcalde (JA).
Breed documented as having blue-/black-/slate-coloured legs, and so the yellow skin allele is believed absent.
Breed documented as having willow-/olive-coloured legs, and so the yellow skin allele is believed present.
Breed documented as having a walnut comb, which is the result of having the alleles for both pea and rose comb.
Phenotype unknown (?), phenotype present (Y), phenotype absent (-).
