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.
O, 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.
