Verified step by step guidance1
Understand that a gene is a segment of DNA that codes for a specific trait, and it can exist in different forms called variants.
Recognize that the term 'locus' refers to the specific physical location of a gene on a chromosome, not the variant itself.
Know that 'chromosome' is the structure that carries many genes, so it is a broader term than a single gene variant.
Identify that 'genotype' refers to the combination of alleles an organism has for a particular gene, rather than the variant itself.
Conclude that the correct term for a different, alternative version of a gene is 'allele', which represents the specific variant at a gene's locus.
