Variant

Variant is a term used in various fields to denote a version, form, or type of something that is different in some way from others of the same kind. In the context of biology, a variant refers to an organism that has characteristics differing from the typical form or from the original type. In genetics, a variant refers to a different sequence of DNA compared to the reference sequence in a population.

Biology

In biology, a variant is an individual organism that exhibits characteristics that differentiate it from other members of its species. These differences can be due to genetic variation, environmental factors, or a combination of both. Variants can occur in both plants and animals, and they play a crucial role in evolution and biodiversity.

Genetics

In genetics, a variant is a DNA sequence that is different from the reference sequence. Variants can occur in both the genome and the exome, and they can have various effects on an organism's phenotype. Some variants are benign, while others can cause diseases or increase the risk of diseases. Genetic variants are studied in the field of genomics and genetic epidemiology.

Other uses

The term variant is also used in other fields such as linguistics, where it refers to a version of a language that is different from the standard form. In computer science, a variant is a data type that can hold values of different types.
