Molecular basis: Mundy et al. (2004): "A nonsynonymous point substitution (Val85>Met85) in the MC1R gene was perfectly associated with the blue phenotype throughout the entire range of lesser snow geese across North America . . . . All blue geese sampled (N = 91) were heterozygous or homozygous for the Met85 allele, whereas all white geese (N = 116), were homozygous for the Val85 allele."

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
