Correct Answer: B
Solution :
For a plant with codominant alleles, both characteristics will show, unless the plant has identical alleles. In this case, both the phenotypic and genotypic ratio will be the same. Therefore, the answer could be either [a] or [d]. In case of the option [d], there is only 2 types of outcome, but with 2 alleles, the outcome should be 3 different types. Hence, the answer should be [a].You need to login to perform this action.
