I-Lokus Rassebestimmung Different dog breeds with genotype

Different dog breeds with genotype e/e express different colour shades from light cream (Golden Retriever) to deep red (Irish Setter)

clinical signs and phenotypic features

allele d3: is present in Chihuahua

ACHM develops due to genetic defects which results in complete loss of cone function and activity of ion channel which is a key mediator in signal transduction in retinal receptors

GRMD is usually expressed around 8 weeks of age

I-Lokus Rassebestimmung Different dog breeds with genotypeI Locus controls the intensity of the red pigment in dogs through affecting the expression of the pheomelanin pigment. This means that recessive I allele is responsible for cream, cream white or pure white coat colour. In dogs there are two types of pigment that create coat colour: eumelanin and pheomelanin. While the eumelanin is a dark pigment causing black coat colour, the pheomelanin is a red pigment. I Locus causes so called extreme dilution of
