Adaptive evolution: the struggle for dominance.
Although wild-type alleles are generally dominant over mutant alleles, recently established alleles for pesticide resistance are rarely recessive in combination with their progenitors. This seems to be caused by a combination of a 'selective sieve' favouring non-recessive mutations, and the biochemical basis of resistance.
