Understand the definition of an allele: An allele is a specific version or variant of a gene that can exist at a particular locus on a chromosome.
Recognize that a chromosome is a large structure containing many genes, so it is not an allele itself but rather the location where alleles reside.
Identify that a genotype represents the combination of alleles an organism has for a particular gene (e.g., Aa), not a single allele.
Note that a trait is the observable characteristic resulting from the expression of one or more alleles, not the allele itself.
Conclude that the correct example of an allele is a version of a gene, such as A or a for a flower-color gene, because these represent the different forms that gene can take.
