Locus Cocoa
£45.00
The cocoa colour comes from a mutation in the HPS3 gene, which affects melanin production and results in a deeper brown shade than typical TYRP1-based chocolate. It’s inherited recessively, so two copies of the HPS3 variant are needed to show the colour, while carriers look normal but can pass it on.
Locus Cocoa (HPS3 gene)
The cocoa colour is caused by a mutation in the HPS3 gene, producing a darker, richer brown shade than the typical TYRP1-based chocolate.
How it works:
-
Cocoa is recessive
-
A dog must inherit two copies of the HPS3 variant (cocoa/cocoa) to show the cocoa colour
-
Dogs with one copy are carriers – they look normal but can pass the variant to their offspring
Appearance:
-
Cocoa can look very similar to other brown colours
-
Genetic testing is the only reliable method to distinguish cocoa from TYRP1 chocolate
