The specific physical location of a gene on a chromosome is known as:

Explanation:
The term locus refers to the specific physical location of a gene on a chromosome. Knowing a gene’s locus helps map where it sits along the chromosome, which is important for understanding inheritance patterns. An allele is a variant form of a gene that can occupy that same locus, often contributing different traits. The centromere is the part of the chromosome where the two chromatids attach during division, not the gene’s position. The telomere is the protective cap at the end of a chromosome. So the correct concept is locus.
