DETERMINATION OF GENETIC DISTANCE BETWEEN HALF-BRED HORSE POPULATIONS IN RELATION TO THEIR COAT COLOUR
Ryszard Pikuła, Dominik Gronet
ABSTRACT
Polymorphic blood image of the horses was used to determine genetic distances between groups of horses of different colour. The study covered 1247 half–bred horses, for which the polymorphism of albumin (Al), transferrin (Tf), alkaline esterase (EspH 8.5), vitamin D binding protein (Gc) and Xk protein were determined. The analysis of genetic distance demonstrated that the studied groups of horses were considerably genetically separated depending on the colour. This allows concluding that there is an association between genetic polymorphism of some blood proteins and the coat colour of horses.
Key words: horses, coat colour, genetic distance, polymorphism of blood proteins.
