2. a distinctive behavior pattern.
sickle cell trait the condition, usually asymptomatic, of being heterozygous for hemoglobin S; see also sickle cell.

trait

(trāt),
1. A qualitative characteristic.
2. A discrete attribute as contrasted with metric character. A trait is amenable to segregation rather than quantitative analysis; it is an attribute of phenotype, not of genotype.

trait

Etymology: Fr, trace
1 a characteristic mode of behavior or any mannerism or physical feature that distinguishes one individual or culture from another.
2 any characteristic quality or condition that is genetically determined and inherited as part of a specific phenotype. A trait is inherited as homozygous dominant, homozygous recessive, or heterozygous in the ratio of 1:2:1 among offspring of two heterozygous parents. In medicine the term trait is used specifically to denote the heterozygous state of a recessive disorder, such as the sickle cell amemia. See also dominance, gene, Mendel's laws, recessive allele.

trait

Genetics An attribute or characteristic of an individual in a species for which heritable differences can be defined. See Bipolar trait, Complex trait, Heritability, High-sensation seeking trait, Input trait, Output trait, Sickle cell trait, Species.
