What is another word for allele?
Pronunciation: [ɐlˈiːl] (IPA) 
Alleles are forms of a gene that can exist at a specific location on a chromosome. Other synonyms for allele include variant, genotype, and gene variant. These synonyms all refer to the variations in DNA sequences that can give rise to different phenotypes. The human genome contains millions of different alleles that can code for different versions of protein or RNA molecules, or that can affect gene expression or regulation. Research on allelic variation has been important for understanding human evolution, genetic diversity, and genetic disease risk. By studying the distribution and function of alleles in different populations, scientists can learn more about how genetic variation affects health and disease.
