Summary Pigmentation genes such as TYR ( tyrosinase ), TYRP1 ( tyrosinase‐related protein 1 ) , DCT (previously TYRP2 , or tyrosinase‐related protein 2 ) , ASIP ( agouti ) and MC1R ( melanocortin receptor 1 ) play a major role in cattle coat colour. To understand the genotypic profile underlying coat colour in native Korean Hanwoo cattle and Angus black cattle, portions of the above‐mentioned genes were amplified. Sequence analysis revealed variation in the TYRP1 (exon 5) and MC1R genes. Restriction enzyme analysis of these two genes could distinguish between different colours of Hanwoo cattle. Quantitative estimates of melanin and eumelanin in hair from three different‐coloured Hanwoo phenotypes and Angus black showed significant differences at the breed and phenotypic levels. Finally, sequence variants in MC1R were associated with total melanin and eumelanin in breeds as well as in Hanwoo phenotypes.
