交配特征和择偶偏好往往表现出在种群和物种之间紧密对应的模式。这些明显的协同进化模式可能是由性状和偏好之间的遗传关联（即性状偏好遗传协方差）造成的。我们回顾了有关特质偏好协方差的文献，以确定其普遍性和潜在的生物学相关性。在我们确定的43项研究中，令人惊讶的是，63%检测到协方差。我们测试多个假设的因素，可能会影响检测此协方差的可能性。主要的预测因素是择偶偏好的遗传变异的存在，这是建立协方差所需的三个主要条件之一。事实上，在偏好遗传力高的9项研究中，89%的研究发现了协方差。变量有关的实验方法和类型的特征，在不同的研究并没有很大的影响检测的特征偏好协方差。性状偏好的遗传协方差似乎是广泛的，因此代表了一个重要的，目前低估的因素，在性状和偏好的共同进化。
Mating traits and mate preferences often show patterns of tight correspondence across populations and species. These patterns of apparent coevolution may result from a genetic association between traits and preferences (i.e. trait–preference genetic covariance). We review the literature on trait–preference covariance to determine its prevalence and potential biological relevance. Of the 43 studies we identified, a surprising 63% detected covariance. We test multiple hypotheses for factors that may influence the likelihood of detecting this covariance. The main predictor was the presence of genetic variation in mate preferences, which is one of the three main conditions required for the establishment of covariance. In fact, 89% of the nine studies where heritability of preference was high detected covariance. Variables pertaining to the experimental methods and type of traits involved in different studies did not greatly influence the detection of trait–preference covariance. Trait–preference genetic covariance appears to be widespread and therefore represents an important and currently underappreciated factor in the coevolution of traits and preferences.
