Temat: INHERITED COAT COLORS OF THE AUSTRALIAN CATTLE DOG
...- D GENE LOCUS: (dilution of pigment) This gene has an effect on both eumelanin and phaeomelanin. When in the dominant form, "D/D" or "D/d", it allows for full color (black or red). When present in the homozygous recessive form (d/d) it dilutes black (eumelanin) to blue, and red to cream. COMBINATIONS OF B AND D IN EUMELANISTIC COATS: The effects of these 2 genes, when combined, form a range of 4 eumelanistic ('black-based') colors: The color of the pup/dog (Eumelanistic Color): B/B D/D or B/b D/d will be black in color B/B d/d or B/b d/d will be blue in color b/b D/D or b/b D/d will be brown/Chocolate (called red in Kelpies) b/b d/d will be flat or dull diluted brown/chocolate (called fawn in Kelpies). ALBINO - C GENE: (development of pigment) The intensity of melanin production in the coat hairs is affected by this gene. The dominant form, "C", is termed 'full color'. At this locus, almost all dogs are...
