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.

Etymology

Origin of recessive

1665–75; < Latin recess ( us ) ( see recess) + -ive

Explanation

A recessive gene is a gene that can be masked by a dominant gene. In order to have a trait that is expressed by a recessive gene, such as blue eyes, you must get the gene for blue eyes from both of your parents. You might remember the word recessive from biology, where it most often appears. Its opposite is dominant and is always living in its shadow. A recessive allele has to team up with another recessive allele in order to show up. We can also use recessive to describe something that has the tendency to withdraw or recede, or something pertaining to an economic recession.

Example Sentences

Some alleles are dominant, meaning their traits are expressed, while others are recessive and remain hidden when paired with a dominant allele.
