The Genetic Basis
For a horse to be born Roan Splash White 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.
- Since the Roan gene is dominant, at least one parent was necessarily Roan (Rn).
- The Splash White pattern was inherited from at least one parent carrying the (Sw2) allele.
Understanding the Alleles
The horse Roan Splash White 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.
- Rn/ (Roan): aaaaaaaaaaaaaaaa
- Sw2/ (Splash White): White patches rising from the lower body, often associated with blue eyes.
