Is it farther or further?
late 15c., "shot, missiles;" later "a stroke, short line" (1580s), from Middle French trait, from Latin tractus "draft, drawing, drawing out," later "line drawn, feature," from past participle stem of trahere "to pull, draw" (see tract (n.1)). Sense of "particular feature, distinguishing quality" is first recorded 1752, from meaning "line, streak, feature" (1560s), which is common to English, French, and Latin.
A characteristic, especially one that distinguishes an individual from others.
A genetically determined characteristic or condition. Traits may be physical, such as hair color or leaf shape, or they may be behavioral, such as nesting in birds and burrowing in rodents. Traits typically result from the combined action of several genes, though some traits are expressed by a single gene.
in biology, any observable feature, or trait, of an organism, whether acquired or inherited. An acquired character is a response to the environment; an inherited character is produced by genes transmitted from parent to offspring (their expressions are often modified by environmental conditions). One gene may affect many characters; one character may be controlled by many genes. A character controlled by only a few genes is known as an oligogenic, discontinuous, or qualitative character; a character controlled by many genes is termed polygenic, continuous, or quantitative. A genetically controlled character may be termed dominant when its controlling genes are powerful enough to mask the effect of other genes (alleles) that control an alternative character, termed recessive
