A recessive trait is a trait that is expressed when an organism has two recessive alleles, or forms of a gene. Traits are characteristics of organisms that can be observed; this includes physical characteristics such as hair and eye color, and also characteristics that may not be readily apparent, e.g. shape of blood cells.

Recessive, as related to genetics, refers to the relationship between an observed trait and the two inherited versions of a gene related to that trait. Individuals inherit two versions of each gene, known as alleles, 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.
A recessive gene is a gene that is expressed only when an individual inherits two copies of it, one from each parent. In other words, a recessive gene remains hidden in the presence of a dominant gene.
