This means that for a specific trait, there are more than two possible variations of the gene.

It's important to note that:

* An individual still only has two alleles for a specific gene, one from each parent.

* The presence of multiple alleles increases the possible combinations of genotypes and phenotypes, leading to greater genetic diversity.

A classic example is the ABO blood group system in humans, where there are three alleles: I^A, I^B, and i. These alleles combine to form the four blood types: A, B, AB, and O.
