The main objective of this study is to investigate the distribution of coat color among Ulleung Korean Native Brindle Cattle, and to identify basic genetic elements required for the fixation of coat color traits. 1. The distribution of coat color among Ulleung Korean Native Brindle Cattle was 24.3% yellow (67/276),13.0% black (36/276), 62.7% brindle (173/276). The frequency of Brindle coat color was slightly higher (66%, 105/159) among embryo transfer from outside than that of cows produced by embryo transfer from jurisdiction. 2. Investigation of coat color distribution in each sex group showed that the frequency of yellow coat color was lower in males (18.1%, 25/138) than in females (31.4%, 43/137). On the other hand, the frequency of brindle coat color was slightly higher among males (68.1%, 94/138) than in females (56.9%, 78/137). 3. Examination of Brindle coat color expression based on the intensity of black dots on the nose indicated that the expression of black coat color increase in proportion to the intensity of black dots.
