locus

1. (in many legal phrases) a place or area, esp the place where something occurred
2. Maths a set of points whose location satisfies or is determined by one or more specified conditions
3. Genetics the position of a particular gene on a chromosome

Locus

 

a linear section of a chromosome occupied by a gene.

Using genetic and cytological methods, it is possible to determine the location of a gene, that is, to find which chromosome contains the given gene and its locus, or position in relation to other genes on the same chromosome. It has been demonstrated in some microorganisms that genes that control a particular sequence of biochemical reactions are found in neighboring loci, which are arranged in the same order as the order in which the reactions occur. This has not been established for higher organisms. The term “locus” is sometimes used in the literature as a synonym for the terms “gene” and “cistron.”
