一个两个位点,两个等位基因的群体遗传模型被用来研究是否一个等位基因的配偶选择复制可以成为固定在一个群体中时,它没有直接的健身效益,因此没有成本,由于选择。所有的女性都对具有某种特征的男性有一种内在的偏好。如果他们有复制等位基因,他们会根据对年长群体交配模式的观察来修改这种偏好。我们的特定模型提出了一个普遍的规则:复制等位基因传播时,复制导致女性交配男性具有较高的总终身健身。因此,当雌性对高生存能力的雄性(好基因)有预先存在的偏好时,以及当雌性复制对损害雄性生存的特征的偏好时,复制都有可能进化。即使存在针对复制等位基因的轻微直接选择,复制也可以通过间接选择的力量传播。
A two-locus, two-allele population genetic model is used to study whether an allele for mate choice copying can become fixed in a population when it has no direct fitness benefit and there is therefore no cost due to choice. All females have an intrinsic preference for males with a certain trait. If they have the copying allele, they modify this preference on the basis of observations of an older cohort's mating patterns. Our specific model suggests a general rule: copying alleles spread when copying causes females to mate males that have higher total lifetime fitness. It is therefore possible for copying to evolve both when females have preexisting preferences for high-viability males (good genes) and when females are copying a preference for a trait that impairs male survival. Copying can spread through the force of indirect selection even when there is mild direct selection against the copying allele.
