D

Verified step by step guidance1
Understand that a gene is a segment of DNA located at a specific position, called a locus, on a chromosome.
Recognize that genes can have different versions or variants, which can lead to variations in the traits they influence.
Learn that these different versions of a gene at the same locus are called alleles.
Distinguish alleles from other genetic terms: a codon is a sequence of three nucleotides coding for an amino acid, a chromatid is one half of a duplicated chromosome, and phenotype refers to the observable traits of an organism.
Therefore, the term that specifically refers to different versions of a gene at a given locus is 'allele'.
