Verified step by step guidance1
Understand the question is asking for the term that describes different versions of a gene.
Recall that a gene is a segment of DNA that codes for a specific trait, but this gene can have variations.
These variations or different forms of the same gene are called 'alleles'.
Phenotypes refer to the observable traits or characteristics resulting from gene expression, not the gene versions themselves.
Chromatids are duplicated chromosomes, and genomes refer to the complete set of genetic material, so neither term fits the description of different gene versions.
