Abstract

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.

摘要

虽然野生型等位基因通常对突变等位基因呈显性，但最近确定的抗农药等位基因与其祖先组合时很少呈隐性。这似乎是由有利于非隐性突变的“选择筛”和抗性的生化基础共同造成的。
