Genotyping of coat color genes (MC1R, ASIP, PMEL17 and MATP) polymorphisms in cold-blooded orses bred in Poland reveals sporadic mistakes in phenotypic descriptions
Journal Title: Animal Science Papers and Reports - Year 2013, Vol 31, Issue 2
Abstract
Equine coat color is an important phenotypic trait, predominantly within the context of correct animal identification. Due to the increased import of horses to Poland during the last years, uncommon coat colors seem to occur more often. In this study, we have analyzed the genotypes of cold-blooded horses representing four breeds (Polish Cold-blooded Horse, Belgian Draft Horse, Percheron Horse and Ardennes Horse) for genes determining basic coat colors (MC1R and ASIP) as well as silver and cream dilutions (PMEL17 and MATP). We have also compared the results of our molecular study with the coat color of each horse listed in the breeding documents. Uneven distribution of genotypes between the investigated groups was observed. Moreover, we have identified several mistakes in coat color descriptions of horses, which justifies the necessity for genetic testing, particularly in case of coat colors difficult to categorize “by eye”. We also suggest to extend the list of horse coat colors recognized by the Polish Horse Breeders Association.
