The Genetic Basis
For a horse to be born Paint Dun Smoky Cream, it must receive the following combination from its parents:
- Its ability to express or produce black pigment indicates it received the dominant E allele from at least one parent.
- To be visually black, it needed to inherit the absence of Agouti (a) from both sire and dam.
- Its blue eyes and pink skin (Double Cream) reveal that both parents were diluted and each passed their Cream gene on.
- The dark dorsal stripe and primitive markings came from at least one parent (D).
- The Tobiano patches that characterize the Paint Horse were inherited from at least one parent.
Understanding the Alleles
The horse Paint Dun Smoky Cream has a specific combination of alleles. Below, we explain each genetic component that forms this coat:
- a/a (Non-Agouti): Allows black to spread over the entire body when combined with E. In e/e animals it is invisible but still passed on.
- Cr/Cr (Double Cream): Intense dilution. Pink skin and light eyes such as blue.
- D/ (Dun): Adds primitive markings (dorsal stripe) and may slightly lighten the base color.
- To/ (Tobiano): Vertical white patches crossing the back.
