Detailed explanation-1: -Locus. 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.

Detailed explanation-2: -Locus. Locus is the physical position a gene or a factor occupies on the chromosome.

Detailed explanation-3: -A locus refers to the location on the chromosome where the gene is found. Loci is the plural form of locus. The gene is located within a designated region on the chromosome and is composed of the different base pairs (GATC) that will give genetic instructions to the plant.

Detailed explanation-4: -A specific position along a chromosome is called a locus. Each gene occupies a specific locus (so the terms locus and gene are often used interchangeably). Each locus will have an allelic form (allele). The complete set of alleles (at all loci of interest) in an individual is its genotype.

Detailed explanation-5: -A gene’s molecular address pinpoints the location of that gene in terms of nucleotides. It describes the gene’s precise position on a chromosome and indicates the size of the gene. Knowing the molecular location also allows researchers to determine exactly how far a gene is from other genes on the same chromosome.
