Detailed explanation-1: -Locus is a term that we use to tell us where on a chromosome a specific gene is. So it’s really the physical location of a gene on a chromosome. It’s a way of defining the gene’s neighborhood.
Detailed explanation-2: -In genetics, a locus (plural loci) is a specific, fixed position on a chromosome where a particular gene or genetic marker is located.
Detailed explanation-3: -(LOH-kus) The physical site or location of a specific gene on a chromosome.
Detailed explanation-4: -Explained in greater detail, each gene resides at a specific locus (location on a chromosome) in two copies, one copy of the gene inherited from each parent. The copies, however, are not necessarily the same. When the copies of a gene differ from each other, they are known as alleles.
Detailed explanation-5: -Because loci are located on chromosomes, and we inherit one chromosome from each of our parents, each locus has two alleles. These alleles can recombine from generation to generation to produce different genotypes.
