Answer 2

The correct answer would be multiple alleles.

Multiple allele refers to the condition in which a gene exists in more than two alternative forms in a population that is, it has more than two alleles.

Different allele may provide different traits to the organism.

For example, in humans, blood types or groups are determined by three alleles
`I^(A)`,
`I^(B)` and i.

Three alleles produce four types of blood groups (phenotypes) which are A, B, AB, and O.
