Answer:
Codominance
Explanation:
When we say codominance, both traits of the parents are seen on the offspring. For example in your problem, the offspring is speckled meaning there is a mixture of both white and black, traits coming from each parent.
Do not confuse this with incomplete dominance. Incomplete dominance is similar but the difference is that the traits are "BLENDED". So let's say that if incomplete dominance occurred, the offspring would be gray.
