In genetics, what is the term for a different form of the same gene, such as T and t?

Explanation:
Think about how traits are controlled by genes that can come in different forms. The term for a different form of the same gene is allele. T and t are two versions of the same gene that determines the trait, and they occupy the same location (locus) on homologous chromosomes. Chromosome is a structure carrying many genes, locus is the exact spot of a gene, and phenotype is the observable trait. So the best term to describe these different forms is allele.
