Coat colour in cattle is controlled by a wide range of different genes working together. These genes are often referred to as ‘loci’. The Extension, or E-Locus, corresponds to the gene ‘melanocortin 1 receptor’ (MC1R), which is involved in the regulation of pigment production. Mutations on the E-Locus often result in a red coat colour in affected animals.

This specific test analyses the variant mutation designated as E^BR, also known as the Telstar Factor.
