Word Origin and History for recessiveness
Online Etymology Dictionary, © 2010 Douglas Harper
- Tending to go backward or recede.
- Of, relating to, or being an allele that does not produce a characteristic effect when present with a dominant allele.
- Of, relating to, or being a trait expressed only when the determining allele is present in the homozygous condition.
- A recessive allele or trait.
- An organism having a recessive trait.
- 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.
