An allele is one of the variant forms of a [[gene]] at a particular locus, or location, on a [[chromosome]]. Different alleles produce variation in inherited characteristics such as hair color or blood type. In an individual, one form of the allele (the dominant one) may be [[expressed]] more than another form (the recessive one)
