WebAnother example occurs when the recessive allele is linked to an allele of a different gene that has a large fitness advantage — since recombination rarely separates the two alleles, this can result in the "bad" allele persisting or even increasing in the population. This is known as "genetic hitchhiking", for more see: WebAllele. An 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. The word "Allele" is a short form of "allelomorph". jeronimo av atlantica bc
