Evolutionary conflict occurs when the deterministic spread of an allele lowers the fitness either of its bearer or of other individuals in the population, leading to selection for suppressors. Sex promotes conflict because associations between alleles are temporary. Differing selection on males and females, sexual selection, and differences in transmission patterns between classes of nuclear and cytoplasmic genes can all give rise to conflict. Inert Y chromosomes, uniparental inheritance of cytoplasmic genes, mating strains and sexes, and many features of sexual behavior may have evolved in part as a result of evolutionary conflict. Estimates of its quantitative importance, however, are still needed.
当一个等位基因的确定性传播降低了其携带者或种群中其他个体的适合度，从而导致对抑制因子的选择时，就会发生进化冲突。性会促进冲突，因为等位基因之间的关联是暂时的。对雄性和雌性的不同选择、性选择以及核基因和细胞质基因类别之间传递模式的差异都可能引发冲突。惰性Y染色体、细胞质基因的单亲遗传、交配型和性别，以及性行为的许多特征可能部分是进化冲突的结果。然而，仍需要对其数量重要性进行估计。
