Locus (genetics) A locus (plural loci) in genetics is the position on a chromosome. Each chromosome carries many genes; humans' estimated 'haploid' protein coding genes are 19,000-20,000, on the 23 different chromosomes. A variant of the similar DNA sequence located at a given locus is called an allele.
Definition: The locus of all points that are equidistant from a given point (focus). and a given line (directrix). Try this Drag the point P. It will move through all the points equidistant from the focus point and the directrix line. Recall that the definition of locus is the set points that meet some given conditions. In this definition of a parabola, it is the shape created by the points that are the same distance from a given point (call the focus) and a given line (called the directrix)*.
