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).

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.
What is a functional locus? Understanding the genetic basis of …
From the last example we can define a functional locus as the whole set of genomic regions that are alternatively used to carry out the same function. Regulatory regions may be also an example of different DNA regions belonging to the same functional locus.

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.
