Q24

q24 is a designation used in several different domains, and it does not refer to a single, universal topic. In genetics, q24 is part of the cytogenetic nomenclature used to describe the position of loci on the long arm of a chromosome. The q indicates the long arm, and 24 refers to a specific band within that arm. A complete reference in standard notation would usually include the chromosome number (for example, 1q24 or Xq24). The standalone q24 is typically shorthand within a discussion of a particular region.

In transportation, q24 is employed as a route or service number by some public transit authorities. Prefixes like Q are used to identify routes in certain cities or regions, and the exact route, schedule, and endpoints are determined by the local agency and can change over time. A given agency may reuse or retire the designation.

In product cataloging and electronics, q24 appears as a model number, part code, or serial designation across different manufacturers. Such usage is independent of other domains, and the same sequence may reference unrelated items.

Because q24 has multiple, context-dependent meanings, precise identification requires additional information about the field and geographic jurisdiction. See also: disambiguation of "Q24."
