Answer: Cows that have a spotted coat have a roan coloring. Both genes are expressed. This pattern of inheritance is a result of codominance

Explanation: Every trait is controlled by a gene that occurs in pair. An allele is a different form of a particular gene. Alleles can be dominant or recessive. A dominant gene is one that is able to express itself in the presence of a recessive gene or is able to mask the effect of the other gene. A recessive gene is one whose effect is masked by a dominant gene. When two genes equally express themselves outwardly, they are said to be codominant.

Codominance is a situation whereby neither of the genes is completely dominant rather both express themselves equally phenotypically. In codominance, one gene is not capable of masking the effect of the other.
