Examples of dilution phenotypes observed in the F2-Backcross individuals. A. Calves with partially diluted red and black coat colour background (scored as Grey and Light-Red) together with a non-diluted individual (scored as Black). The SILV c.64A>G mutation showed significant association with the dilution phenotypes (p-value < 0.001). B. Two calves showing completely diluted phenotypes (scored as White). For the animal on the left, the genotype of the SILV c.64A>G mutation was not consistent with the presumed genotype at the Dc locus. For discrepancies like this, however, no convincing recombination between SILV c.64A>G and the Dc locus was observed.
