If you are talking about two different traits (lets say skin color, caucasian and African American) combining to make a “middle” color (golden tan), it would have to do with incomplete dominance. The traits appearances are not dominant over each other so neither are fully expressed. Some examples of incomplete dominance are: skin color, hair body (curly, wavy, straight), and height in humans. Another type of blending of traits has to do with co-dominance. Co-dominance is the expression of both dominant traits creating a splochy appearance of both traits. Do not confuse this with freckles which is a different trait on its own.
