The karak suit of the horse, the photo of which you will see in our article, is considered to be one of the most common. But until now, scientists can not figure out why this is so. Let's try to deal with this fact and some other nuances.
I can argue that most breeders are bay horses and have no idea that their horses can belong to karak colors. The fact is that it is rather difficult to distinguish these suits, especially if the horse is dark-bay. But there is one feature, this option is the darkest color of all the bay. It turned out as a result of a combination of black and bear suit.
Its representatives are characterized by dark, almost black mane, tail and body. And under the armpits, in the groin area, on the neck, around the eyes and lips, there are brown tan spots. Only thanks to the latest karak horses can be distinguished from the dark-bay. Also thanks to such a scorch, they are also called black in the sun. In addition, there may be white markings on the head and legs.
Another interesting fact is that scientists do not yet know which gene is responsible for such pigmentation of the body in a karak horse. But still there are a number of hypotheses, among which there is one more or less plausible. She was stuck out by a certain Castle. As he claims, the gene that is dominant in the suit is the subspecies of agouti. As an example, he cites mice in which a variety of agouti exceeds 100 variants.
According to the theory of this genetics, the aguta locus has 4 genes, these are: A +, A, a (t), a. In accordance with this assumption, it follows that the A + gene is responsible for the “wild” variation of the bay coloration, and the usual bay collar is A, and the Karaka is a (t), and the black one is a. According to theory, these four genes dominate each other. The first and most important is A +, then A goes, then - a (t), and the weakest is a. That is, the “wild” bay is considered the strongest suit, while the weakest is the black one. But until the hypothesis is proven, until it remains just an assumption, based on this, it is up to you to believe it or not.
Also quite interesting is the fact that Karak horses do not have otmastok or other shades. But sometimes small apples can be found on the body. Their appearance is associated with proper diet and good horse care.
