我们使用一般加性定量遗传模型，通过“障碍”原则来研究代价高昂的女性择偶的进化。 代价偏好的形成必须满足两个必要条件。 条件是（i）对生存力的偏置突变压力和（ii）雄性交配性状的表达程度与生存力之间的直接关系。 这两个条件解释了“障碍”原则先前模型的成功和失败。 我们的模型也适用于其他来源的适应度变化，如迁移和宿主-寄生虫的共同进化，这会导致相当于偏见突变的影响。
We use a general additive quantitative genetic model to study the evolution of costly female mate choice by the "handicap" principle. Two necessary conditions must be satisfied for costly preference to evolve. The conditions are (i) biased mutation pressure on viability and (ii) a direct relationship between the degree of expression of the male mating character and viability. These two conditions explain the success and failure of previous models of the "handicap" principle. Our model also applies to other sources of fitness variation like migration and host-parasite coevolution, which cause effects equivalent to biased mutation.
