Group A and B mtDNA control-region haplotype frequencies and ornithine decarboxylase intron six (ODC-6) allele and genotype frequencies, including observed and expected frequencies, for Eastern Spot-billed Ducks and Mallards from Primorye, Russia. Samples sizes for the control region were 36 spot-bills and 82 Mallards, whereas samples sizes for ODC-6 were 37 spot-bills and 83 Mallards (the two phenotypic hybrids were classified as spot-bills).
