Description

The Co-Locus is a region of your dog's DNA which controls a brown/chocolate coat colour present in French Bulldogs known as cocoa. The cocoa colouring generally tends to be darker than the chocolate produced by the B-locus though this can vary depending on the combination of other colour genes.

Your dog can only be cocoa if they are also E/E or E/e on the E-Locus. The Co-Locus behaves in a similar way to the B-locus meaning you can have solid cocoa colour as we all, for example, cocoa and tan.

The cocoa colour is controlled by mutations on the HPS3 gene.

Results:

Your results will be reported as one combination of the I-locus alleles with the following interpretations.

N/N - no cocoa
N/co - not cocoa - carrying cocoa
co/co - cocoa
