Brown (Chocolate and Cinnamon)
The Brown gene affects the amount of black (eumelanin) pigment produced. Mutations responsible for brown and cinnamon colours in the cat have been identified in this gene. The wild-type B allele produces normal, black coloration. The b allele produces the brown (chocolate) phenotype and the bl allele produces a light brown or cinnamon phenotype. These form an "allelic series" with B dominant to b, and b dominant to bl.
Requirements
The tests are performed out of EDTA whole blood (0.5 ml) or cotton swabs. These cotton swabs are available upon request. Testing is performed a few times per week at Laboklin. The results are due about one week after arrival of the sample in our laboratory.
