Summary Six plasma eserine resistant esterase phenotypes were observed in a population of 1438 dogs consisting of 38 breeds. Analysis of parentage records of the dogs examined revealed that the phenotypic variation of eserine resistant esterases was controlled by 3 codominant alleles Es A , Es B and Es C at one autosomal locus. The gene frequency of Es B was high in most of the breeds examined. Allele Es C was only seen in 5 Japanese native breeds, Akita, Shikoku, Hokkaido, Shinshu‐Shiba and Mino‐Shiba, and in a Spitz dog. Allele Es A has a low frequency in Japanese breeds but a higher frequency in some of the European breeds tested.
