The word locus (plural loci) is Latin for "place".
In biology and evolutionary computation, a locus is the position of a gene (or other significant sequence) on a chromosome. A locus can be occupied by any of the alleles of the gene.

Locus
The position of a gene on a chromosome or other chromosome markers; also, the DNA at that position. The use of the term locus is sometimes restricted to main regions of DNA that are expressed. Plural: loci. See gene expression.

Locus: 7q31.2 - The CFTR gene is found in region q31.2 on the long (q) arm of human chromosome 7.
Gene Structure: The normal allelic variant for this gene is about 250,000 base pairs (bp) long and contains 27 exons.

A locus (plural: loci) is the location of a gene on a chromosome. The gene for red flowers and the gene for white flowers are two different alleles at the same locus.

Directional selection depletes genetic variation at the selected locus as the fitter allele sweeps to fixation. Sequences linked to the selected allele also increase in frequency due to hitchhiking.

X-inactivation requires a locus on the X, called the X-inactivation center. At this locus, inactivation occurs in response to a developmental cue, which is present only at specific stages of embryo development.
