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.
Best Answer: In biology and evolutionary computation, a locus is a fixed position on a chromosome, such as the position of a gene. A viable DNA coding at a given locus within a gene is called an allele.The ordered list of loci known for a particular genome is called a genetic map.iploid and polyploid cells whose chromosomes have the same allele at some locus are called homozygous, while those that have different alleles at a locus, heterozygous. Nomenclature The chromosomal locus of a gene might be written 6p21.3.
