recessive in Science

recessive

[rĭ-sĕsĭv]
  1. Relating to the form of a gene that is not expressed as a trait in an individual unless two such genes are inherited, one from each parent. In an organism having two different genes for a trait, the recessive form is overpowered by its counterpart, or dominant, form located on the other of a pair of chromosomes. In humans, lack of dimples is a recessive trait, while the presence of dimples is dominant. See more at carrier inheritance. Compare dominant.
