dominant   (dŏm'ə-nənt)  Pronunciation Key 
  1. Relating to the form of a gene that expresses a trait, such as hair color, in an individual organism. The dominant form of a gene overpowers the counterpart, or recessive, form located on the other of a pair of chromosomes.
  2. Relating to the trait expressed by such a gene. See more at inheritance. Compare recessive.
  3. Being a species that has the greatest effect within its ecological community, especially by determining the presence, abundance, or type of other species. As a plant community progresses through stages of succession, different species may become dominant for a period until the climax community is reached, at which point the dominant species remains stable until a major disruption occurs. Among animals, the dominant species in a community is generally the top predator or the most abundant or widespread species.
  4. Being an animal that occupies the highest position in a social hierarchy and has the greatest access to resources such as food and a mate or mates. Social dominance is gained and maintained through factors such as size and aggressiveness.
