In a codominant inheritance pattern, the alleles for the coat color are expressed simultaneously in the phenotype of the offspring.
In this case:
- CWCW represents the homozygous white horse.
- CBCB represents the homozygous black horse.
When these two horses are bred, all offspring will have the genotype CWCB (heterozygous), which means they will express both colors in their hair, resulting in a roan color.
Therefore, the likelihood that their offspring will be roan with both colors represented in their hair is **100%**.
