Definition: In mathematics, "overdominant" refers to a property that is more important or significant than another. For example, in a group of 50 people, if only 49 people are selected at random and one person is randomly selected from each person, then the probability that all four are overdominant (all four have the same score) would be very low. This implies that there must be some other individual who has a slightly higher score than all the others.
