^a: geographic origin indicated as “P” for Paris, France, and “S” for Saratov, Russia.
^b: the chicken MC1R sequence was used as a reference for the position of the polymorphic nucleotides.
^c: the IUPAC ambiguity code was used to indicate cases where the sequenced individuals were heterozygous.
* indicates a non-synonymous change.
