The I-Locus is a region of your dog's DNA which controls the intensity of colour of the phaeomelanin or yellow/red pigment which is expressed through the E-locus.
Your dog's coat colour intensity will only be affected if your dog is e/e on the E-Locus and thus expressing the yellow coat pigment.
The coat colour intensity is affected by mutations on the MFSD12 gene.
Results:
Your results will be reported as one combination of the I-locus alleles with the following interpretations.
I/I- higher intensity - yellow/redI/i- higher intensity - yellow/redi/i- reduced intensity - cream/white
