Verified step by step guidance1
Understand the definition of a gene locus: it is the specific physical location or position of a gene on a chromosome.
Understand the definition of an allele: it is a variant form of a gene that can exist at a particular gene locus.
Recognize that a gene locus is like an address on a chromosome, while alleles are different versions of the gene that can occupy that address.
Note that gene locus and allele are not synonyms; they describe different concepts—location versus variant form.
Conclude that the correct relationship is: a gene locus is the position of a gene on a chromosome, and an allele is a variant form of the gene found at that locus.
