Study of the influence of the gene-diluent “cremello” on the inheritance of colors in the horses of the akhal-teke breed

Abstract

A wide palette of colors is one of the key features of the Akhal-Teke breed of horses. The phenotypic manifestation of a rare color is due to the influence of the “Cremello” clarifier gene on the synthesis of the main pigments - eumelanin and pheomelanin. In combination with the basic suits, it gives new rare suits – buckskin, palomino, cremello. The increased demand for foals with the clarifier gene stimulates interest in the topic of inheritance of colors. A study of the livestock of the Akhal-Teke breed of horses for the carriage of the “Cremello” diluent gene was carried out, crossbreeding schemes were proposed, and the percentage of the probability of the expected phenotype in the offspring was calculated. Analysis and phenotypic evaluation of the colors of the obtained foals showed that in order to obtain the colors of interest, it is necessary that at least one of the parents be of the Isabella color - the carrier of the Cremello gene in the homozygous state (CcrCcr).
