As an example, say you have a gene that makes an enzyme that catalyzes a necessary chemical conversion in the body. The enzyme 21-hydroxylase is a good example. If you have two alleles that both make a well-functioning 21-hydroxylase enzyme (you are homozygous dominant), you are good.
Popular definitions of 'allele' typically refer only to different alleles within genes. For example, the ABO blood grouping is controlled by the ABO gene, which has six common alleles (variants).
