“…Such marks are not characteristic nor they attest the presence of the dun factor by themselves; often they are not even present in all duns. These appear as: ⁻ Dark bands perpendicular to the dorsal stripe (barbs off the dorsal stripe) that may extend variably toward the ribs; ⁻ Shading on the neck (neck shadow), which can vary from a well-defined mark to only a shadowing; ⁻ Bider marks-a dark band or shadowing varying in shape and extent on the shoulder, identified so far only in some horses from Mongolia [18].…”

Since the dawn of horse domestication, coat colors have always fascinated humankind. In the last century, knowledge of genetics and development of scientific tools have become powerful enough so that the effects of many DNA mutations could be critically studied. Coat color nomenclature varies according to countries and breed associations; in addition, many factors can modify the color of the coat, such as sun exposure, age, sex, and nutritional status of the animal. Nevertheless, horses are capable of producing only two pigments. Several genes have been indicated as putative to coat color modification, altering the basic color by dilution, redistribution, or lacking of pigments.

“…Also, it is possible that there is a novel gene in this population contributing to the coat colour phenotype observed in this population that may be different from the common black coat colour observed in modern horse breeds [3]. Indeed, a number of rare coat colours have been identi ed in Mongolian horse populations that are not found in the more common modern European/American breeds [17]. Since several genomic regions on other chromosomes were identi ed in the Abaga Black (Figure S1 and Table S2), these genomic regions may harbour genes and/or genomic regulatory elements in uencing the coat colour phenotype and other uncharacterised traits in this population.…”

Background: Thousands of years of natural and artificial selection since the domestication of the horse has shaped the distinctive genomes of Chinese Mongolian horse populations. Consequently, genomic signatures of selection can provide insights into the human-mediated selection history of specific traits and evolutionary adaptation to diverse environments. Here, we used genome-wide SNPs from five distinct Chinese Mongolian horse populations to identify genes within genomic regions under selection for traits specific to Wushen (gait), Abaga Black (black coat colour) and Baicha Iron Hoof (hoof quality) horse, as well as other global breeds to identify regional-specific signatures of selection.Results: We first validated the use of the composite selection signals approach by identifying the most significant selection peak for the Wushen horse in the region on ECA23 harbouring DMRT3, the major gene for gait. We detected selection signatures encompassing several genes in the Baicha Iron Hoof horse that represent good biological candidates for hoof health, including the CSPG4, PEAK1, EXPH5, WWP2 and HAS3 genes. In addition, an analysis of regional subgroups (Asian compared to European) identified a single locus on ECA3 containing the ZFPM1 gene that is a marker of selection for the major domestication event leading to the DOM2 horse clade.Conclusions: Genomic variation at these loci in the Baicha Iron Hoof may be leveraged in other horse populations to identify animals with superior hoof health or those at risk of hoof-related pathologies. The overlap between the selection signature in Asian horses with the DOM2 selection peak raises questions about the nature of horse domestication events, which may have involved a prehistoric clade other than DOM2 that has not yet been identified.
