WebAlleles may have superscripts (w a) or subscripts (A 1) or both. In teaching examples, alleles are often designated by capital and lower cases pairs (A & a; B &b). In dealing with eukaryotic, diploid organisms, the genotype for each autosomal gene is designed by a pair of alleles. Thus, the A gene might have genotypes AA, Aa or aa. WebAn allele ( UK: / ˈæliːl /, / əˈliːl /; US: / əˈliːl /; modern formation from Greek ἄλλος állos, "other") is a variation of the same sequence of nucleotides at the same place on a long DNA molecule, as described in leading textbooks on genetics and evolution.
