The relevance of the subject under study is conditioned upon changes in the exchange of melanin in skin cells, which result in unevenly coloured sheep hair. The purpose of this study investigated the nature of depigmentation inheritance of the hair of black Karakul sheep in ontogenesis. The objective method was the main method used in the study. The results of the study showed that the climate was one of the factors for preserving the colour of the desired shade of an adult. Bonitation of young animals according to the pronounced pigmentation of krimmer lamb takes place when the young animals reach the age of one and a half years. During this period pigmentation gradually decreases, and the wool becomes completely white. The originality of this study lies in the analysis of the cellular mechanism of regulation of melanogenesis in sheep. The materials of this paper are of practical value for breeders in controlling a biological phenomenon that affects the quality of the Karakul sheep breed.
