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

Genotypes of the SILV c.64A>G mutation in the F2-Backcross population considered in this study. Distribution of genotypes across the five colour categories defined in this work (A) and across the three genetic background groups of the studied population, CB1, F2 and HB1 (B). Numbers in bold indicate the discrepancies observed in our dataset between the SILV c.64A>G genotypes and the dilution phenotype.
