trait

 [trāt]
1. any genetically determined condition; also, the condition prevailing in the heterozygous state of a recessive disorder, as the sickle cell trait.
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.
[Fr. from L. tractus, a drawing out, extension]

1. A distinguishing feature, as of a person's character.
2. A morphological, physiological, or behavioral feature of an organism.

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.

trait, sickle cell,
n a form of sickle cell disease in which patients are asymptomatic but their erythrocytes can be caused to assume a sickle shape under certain conditions. The trait is present when one parent has the gene (heterozygous condition) for sickle cell disease. See also disease, sickle cell.

2. a distinctive behavior pattern.

trait A-46
see inherited parakeratosis.
qualitative trait
a characteristic that is expressed only in descriptive terms, e.g. fine bone, deep chest.
quantitative trait
a characteristic that is expressed mathematically, e.g. an annual yield of milk of 15,000 lb.
sex-linked trait
the gene for the trait is located on the chromosomes which determine the sex of the individual.
