WebMendel's notation of a capital and a lowercase letter (Aa) for the hybrid genotype actually represented what we now know as the two alleles of one gene: A and a. An allele 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. The word "Allele" is a short form of "allelomorph". "The chromosomal or genomic location of a gene or any other genetic element is called a locus (plural: loci) and alternative DNA sequences at a locus are called alleles."

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.
