Description

This test is for the 'bd', 'bc' and 'bs'variants, which are described in all dog breeds and are responsible for the brown coat colour, which is also known in some breeds as liver, chocolate, chestnut, sedge, and less frequently, red. Two copies of the b-allele are needed to dilute black pigment to brown. For red or yellow dogs, the brown allele does not dilute the hair colour, but will change the colour of nose and foot pads from black to brown if two brown alleles are present.

When one of the variants is found homozygous (bd/bd, bc/bc or bs/bs), dark pigment (eumelanin) is diluted to brown in the pigmented areas. However, when several variants of the B-locus are found in heterozygous state (example N/bd and N/bc), it is not always possible to directly determine the influence on the eumelanin because this depends on whether the variants are located on the same or different chromosmes, however, the dog will definitely pass the variants to its offspring.

Australian Shepherd and Lancashire Heeler

Please note there are two additional rare variants, which are not analysed in this test. The 'b4' variant which is only found in few Australian Shephered lines, and the 'be' variant which is only found in Lancashire Heeler, and therefore for a complete analysis in Australian Shepherd and Lancashire Heeler, you need to order this test in addition to the rare variant test . You can take advantage of our special offer 'second coat colour test at half price (excluding bundles)'.

French Bulldog

In French Bulldog, in addition to the B-locus, the Cocoa gene is also responsible for the brown coat colour, and therefore, in addition to this test you also need to order the Cocoa coat colour test . You can of course take advantage of our special offer 'second coat colour test at half price (excluding bundles)'.
