2/27/2024 0 Comments Bay horaeSooty can also cause very pronounced dappling on the coat. On some colours, such as wild bay, however, the dark hairs seem to be mostly on the lower part of the horse. It can often be characterised by a concentration of dark hairs mainly along the topline of the horse, which is called countershading. Sooty (STY, sty) or smutty is a modifier that causes a darkening of the coat that can be expressed in many different ways. In Horse Reality, the allele causing the pangaré phenotype is dominant. Since the genetics behind pangaré are still unknown, it is not possible to test for the allele responsible for pangaré in-game. It mainly lightens the areas above the muzzle and the eyes, and the underside of the body (flanks, belly). Pangaré (PA), also sometimes referred to as mealy, is a modifier that only affects red pigment. The following modifiers and/or dilutions can act on the bay base coat:ĭifferent modifiers can alter the phenotype of bay-based horses. The current theory in real life is that E/E A/a generally causes dark shades of bay, with the phenotypes of E/E A/A, E/e A/A and E/e A/a being more variable from light-dark. The table below shows all possible combinations of the alleles with their outcomes in-game: The presence of dominant agouti can be tested at the Laboratory, but the wild bay (A +) and seal brown (A t) alleles are hidden and not testable, meaning that their test results will be displayed as just A. The order of dominance between the agouti alleles is A + > A > A t > a. This theory has since been disproven, but in Horse Reality, three different dominant agouti alleles are still used to determine the colours: A + (wild bay), A (bay) and A t (seal brown). In real life, seal brown and wild bay were once believed to be caused by different agouti alleles. The dominant extension allele makes the production of black pigment possible, while the dominant agouti allele is responsible for restricting the black pigment to the points of the horse only. In Horse Reality, the shade of wild bay, bay or seal brown a horse gets once they turn into an adult is determined by chance (outside of the effect of modifiers).Īll bay horses have at least one dominant E (extension) and A (agouti) allele ( E/_ A/_). However, the soft parts of their body (muzzle, eyes, flanks, inside upper parts of legs) remain reddish in colour. They can sometimes be so dark that they resemble black horses. They have a reddish coat, and their shade can vary from a very light mahogany bay to blood bay.
