If a homozygous white horse CWCW and a homozygous black horse CBCB are bred together, what is the likelihood that their offspring will be roan with both colors represented in their hair if this gene follows a codominant inheritance pattern?
The likelihood that their offspring will be roan with both colors represented in their hair is 100% (B). In a codominant inheritance pattern, both traits are expressed equally and are not blended together.
