WebPeople with a sickle cell trait (as opposed to disease) have only one mutated allele. Because they have one normal allele that produces normal hemoglobin, they do not have the symptoms of the full disease. Therefore, we say sickle cell disease is recessive because you only see it in individuals who have both alleles that are abnormal. 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.
