Belarusian carriage horse is descended from a wild ancestor – the forest Tarpan, ranks first among all breeds of the Republic on the multitude, unpretentious, good-natured, well-adapted to the territorial and climatic conditions of Belarus.

A characteristic feature of the breed is the color of the horses. Nearly 60 percent have a fancy buckskin, blue, Palomino, sarasou suit that are stably inherited.

In connection with the development of hobby anilazine, tourist service horses original kinds are in high demand and their percentage in the rock increases. In the process of crossing such "colored" individuals, there are often otmachine that cause difficulty in  their description. Respectively  there is interest in the genetic basis  of the occurrence of such suits and the possible practical application of this knowledge in plant breeding.

Currently, the study of inheritance of colors in horses with the use of modern molecular genetic techniques scientists of many countries of the world: USA, Sweden, Germany, Switzerland, and France.

In the process, discover more genes and mutations affecting a variety of colors, determine the correlation between the color and economically useful traits. Despite the fact that the basis is still the same two pigments ( eumelanin and pheomelanin) and three base colors ( Bay, red, black). Not so long ago the horse identified a number of mutations responsible for lighten only certain parts of the body: for example, almost white mane and tail (Flaxen), podlasly (Pangare), darkening of the body (Sty), special drawing, etc.

The Belarusian draught at present, the most frequent lightening mutations and Cremello Dilution, the manifestation of which is sufficiently well defined visually. Vorono-cream (ash black) horses who have not undergone genetic tests, phenotypic  register as regular blacks, although on closer examination they have a uniform ashy or coffee shade.  the base of the Horse chestnut suit is defined as buckskin (gnida-Isabella), and horse chestnut – like Palomino (tan / Isabella).

Quite often in the breed Isabella found the suit, when the mutation-clarifier, the horse is represented by two alleles, that is, the horse is homozygous for the mutation Cremello, it occurs regardless of whether the original suit of the horse red, chestnut or black.

Mutation  Dilution forms a so-called  sarasou  series  kinds and quite much widespread in the Byelorussian harness breed.  in Addition to clarification of the basic colors it gives horses dirty shades of dark "belt" on the back, the strips (zebroides) on his feet, dark spots-the"wings" on the blades.

In contrast to the "Isabella" clarification and the "single" and "double" dose of the mutant allele has the same effect: horses become black Raven light-brown, light (blue), he has Bay, gneto-sarasou (sarasou), red – red-sarasou (Kaur). Those animals in which sarasot not discovered, are in the genotype recessive alleles dd.

It is believed that sarasou suit inherent indigenous species, and indicate their proximity to the wild ancestors, i.e. minor impact of artificial selection. Of course gene Sarasota went to the Belarusian breed of the Tarpan, which follows from the description of the  kinds wild ancestor.

 If the phenotype of the horse the features of both genes clarifiers, the description suits the horse, you need to specify both.

Less frequently the Belarusian draught found podacast   (gene Pangare) – whitish fur on the muzzle end, in the groins and abdomen, presumably found the Flaxen gene is responsible for lightening the mane and tail have red horses, and received the suit ohrenevali not considered. Found mutation of celosti (Roan) , probably trapped in the rock when crossing the "blood" of heavy rocks. Chalykh horses it is not advisable to cross each other, as this mutation in the homozygous state is associated with a greater percentage of deaths. According to the latest data takes place linked the nature of inheritance of a lethal factor.

Perhaps soon the Belarusian breeders will be available for the study of the genome of horses, including in terms of mutations stripes at low cost. Domestic genetics conduct research of the genome of the horse to confirm the  validity  of origin.

It is very likely that the Belarusian draught  the breed will eventually contribute to the confirmation or refutation of hypotheses about the inheritance of rare kinds.
