Genes can have variations. Alternative sequences {allele}| can be at genetic loci. Bateson and Saunders invented name [1902]. Different alleles make different polypeptides and produce different phenotypes, such as blood types O, A, B, and AB. Haploid organisms have one allele at each locus. For diploid organisms, one allele is from father, and one is from mother.
