Locus (genetics) - Wikipedia
In genetics, a locus (pl.: loci) is a specific, fixed position on a chromosome where a particular gene or genetic marker is located. [1] Each chromosome carries many genes, with each gene occupying a different position or locus; in humans, the total number of protein-coding genes in a complete haploid set of 23 chromosomes is estimated at ...

2023年8月3日 · Locus (plural loci) is a position or place on a chromosome occupied by a particular gene or one of its alleles in all species. A locus can be a coding sequence, a regulatory region, or other regions. Any pair of homologous chromosomes can contain a specific locus.
Locus (Genetics) - SpringerLink
A locus is a spot or “address” on a chromosome at which a gene for a particular trait is located in all members of a species. It can also refer to the location of a mutation or other genetic marker. A given locus can be found on any pair of homologous chromosomes (Brown, 2009).

2020年1月25日 · The location of a gene (or of a significant sequence) on a chromosome or on a linkage map. For example, the locus of the gene OCA1 (or Oculocutaneous Albinism Type 1, the gene associated with albinism) is on 11q1.4-a2.1, which means it is on the long arm of chromosome 11, between sub-band 4 of band 1 to sub-band 1 of band 2.

Hundred of thousands of single nucleotide polymorphisms (SNPs) are genotyped in cases of disease and controls to assess association with a particular disease. Differences on allele frequencies between cases and controls are tested for each genetic polymorphism.

2017年9月20日 · A locus is the physical location of a gene on a chromosome. There may be one or more alleles at a single gene locus. In diploid organisms, there are two copies of each locus on the autosomal chromosomes.
Gene Locus - an overview | ScienceDirect Topics
To define the unique location coding for the gene in the genome, the term “locus” is used. Thus, the number of loci and the sequence of each locus are predetermined specific to each species. Not only the location but also the DNA sequence of each locus are unique and distinctive compared to those of other loci.
Locus | genetics | Britannica
Each locus may be the site of several alleles (alternative genes). In an ordinary cell of the human body, there are 46 chromosomes arranged in 23 pairs, 22 pairs of which are autosomes (chromosomes other than sex chromosomes), with the remaining pair being the…
