A careful walk through the MC1R gene, its signalling pathway, the specific e-allele variants that produce white coat, and what the molecular biology actually tells us about white shepherd health.
Read moreA detailed examination of how the e/e genotype at the MC1R locus affects coat color but leaves skin, nose leather, eye, and lip pigmentation intact in white German Shepherds and Berger Blanc Suisse.
Read moreHow DNA testing identifies the e/e, E/e, and E/E genotypes at the Extension locus in German Shepherds, including test accuracy, laboratory options, and interpreting results for breeding decisions.
Read moreA molecular explanation of how the e/e genotype at the MC1R locus produces white coat color in German Shepherds through normal pigmentation pathways.
