Definition
noun, plural: genetic loci
The location of a gene (or of a significant sequence) on a chromosome or on a linkage map.
Supplement
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.
Word origin: locus ยป Latin stlocus, a place.
Also called: gene locus.

Genes are the blueprint of our bodies, a blueprint that creates a variety of proteins essential to any organism's survival. This tutorial looks at the various factors that affect growth. ..
Genes are expressed through the process of protein synthesis. This elaborate tutorial provides an in-depth review of the different steps of the biological production of protein starting from the gene up to the process of secretion. Also included are topics on DNA replication during interphase of the cell cycle, DNA mutation and repair mechanisms, gene pool, modification, and diseases...
Meiosis is a form of cell division that creates gametes. It is comprised of two divisions that in the end, the resulting cell will contain half the chromosomal number of the parent cell. Know the different stages here...
Mutations involving a gene can similarly be harmful as the chromosomal mutations. This tutorial looks at the mutations occurring at the genes and the harm it may bring. Get to know genetic mutations, such as gene inversions, gene translocations, and DNA sequence alternations...
