一些动物群体，如鸟类，似乎倾向于极端形式的性选择。其中一个影响因素可能是影响雄性展示和雌性偏好的基因的性连锁。在这里，我们表明，性连锁可以有实质性的影响，这些性状之间的遗传相关性，因此费舍尔的失控和良好的基因机制的性选择。在某些类型的性连锁（例如Z连锁偏好）下，离家出走的可能性比常染色体遗传更大，而在其他类型的性连锁（例如，X连锁偏好和常染色体显示），好基因机制特别强大。这些理论结果表明，实证检验的基础上的比较方法。
Abstract Some animal groups, such as birds, seem prone to extreme forms of sexual selection. One contributing factor may be sex linkage of genes affecting male displays and female preferences. Here we show that sex linkage can have substantial effects on the genetic correlation between these traits and consequently for Fisher's runaway and the good-genes mechanisms of sexual selection. Under some kinds of sex linkage (e.g. Z-linked preferences), a runaway is more likely than under autosomal inheritance, while under others (e.g., X-linked preferences and autosomal displays), the good-genes mechanism is particularly powerful. These theoretical results suggest empirical tests based on the comparative method.
