The birth of the tricolor border herding is the wonderful result of the interaction of the mixed color gene and the dilution gene. When we dig deeper into the genetic mechanism behind it, we will find that a pure black and white border herd, no matter what color the border herd is bred with, can only give birth to black and white puppies. However, this does not mean that their offspring will only carry the genes of both black and white. 
When two border herders with black and white appearances but red genes meet, their offspring may appear in both black and white and brown and white. Amazingly, some of these black and white puppies have red genes, while others don't. This is the beauty of genetics, which makes it possible for different shades of edge herding to occur in the same litter of puppies. To breed a tricolor borderherd, we can do so by skillfully combining mixed and diluted genes. However, in this process, we need to make one point clear: in the coat color combination of the three-color border herd, the solid color gene is dominant (black), the dilution gene dominant (functional) mixed color (meteorite) gene is recessive, and the yellow (three-color gene) is dominant. This means that we need to pay attention to the genetic mix to ensure that we can get satisfactory results. 
It is important to note that some colors of borderlander genes are recessive, and they need to be bred with other colors of bordermailing to manifest themselves. For example, a yellow-white and a pure mink can be meteorite in nature, and both yellow-white and pure mink can make the meteorite color that should be unvisible. Therefore, we do not recommend direct breeding of yellow-white or pure mink and meteorite, but rather meteorite-to-meteorite to ensure that the offspring will be able to present the desired tricolor effect. 
To sum up, the birth of the tricolor border herd is a vivid manifestation of genetic diversity. By understanding their genetic mechanisms, we can more effectively breed tricolor border herding with a unique charm.
