Table 1 Distribution of phenotypic coat colour scores across the genetic background groups. Number of animals of each genetic background group (F2, HB1 and CB1) scored in each of the defined coat colour categories (A) and subcategories (B) included in the combined traits analyzed in this study.

From: Genetic effects on coat colour in cattle: dilution of eumelanin and phaeomelanin pigments in an F2-Backcross Charolais × Holstein population
