A farmer crossed male cattle with white hair and female cattle with red hair. Every offspring had roan hair (a blend of red and white). He then kept crossing two roan cattle with each other, and the offspring appeared in the ratio 1 red : 2 roan : 1 white. What accounts for the farmer getting this ratio?
- AThe red phenotype is dominant to the white phenotype.
- BThe roan phenotype is an example of codominance.
- CThe roan phenotype is dominant to the red phenotype and the white phenotype.
- DThe white phenotype is dominant to the red phenotype.
