allery**Multiple alleles** in a population means:
AA gene that controls several traits
BMany genes controlling one trait
CMore than two alternative forms of a gene exist at the same locus
DA gene that has mutated only once
Answer & Solution
Correct answer: C. More than two alternative forms of a gene exist at the same locus
Multiple allelism: a gene exists in more than two alternative forms in a population (e.g. ABO blood groups have I^A, I^B, i — three alleles; Drosophila wing-size alleles include vg, vg^ni, vg^no, vg^st, vg+).
