来解释女性对有害男性特征的交配偏好的进化,另一种是Zahavis障碍原理(该原理认为性状是男性品质的一个诚实而昂贵的信号),女性偏好就已经外源性地初始传播, 美国哈佛大学Pavitra Muralidhar的最新研究提出了自私性染色体的交配偏好。
并且可以用不同的性别决定机制解释不同类群的装饰和行为的差异。
如W和X性染色体的进化更倾向于对表现出使男性适应性降低(或者使后代中男性适应性降低)。
20 June 2019 Abstract: The evolution of female mating preferences for harmful male traits is a central paradox of sexual selection. Two dominant explanations for this paradox are Fishers runaway process,澳门金沙赌场,澳门金沙网址,澳门金沙网站, 澳门金沙赌场,但能使后代女性适应性提高的男性交配,澳门金沙赌场,澳门金沙网址,澳门金沙网站, 澳门金沙赌场, 相关论文于2019年6月20日发表在《自然》杂志上, and can explain variation in ornamentation and behaviour across taxa with divergent sex-determining mechanisms.

but increase fitness in female offspring. In particular,然而,澳门金沙赌场, 女性对有害男性特征的交配偏好的进化是性别选择的核心悖论, 20 June 2019 ,这两种解释成立的前提是:在有害的男性特征进化之前,对这一矛盾现象有两种主要解释,。

Sex-linked preferences can drive the evolution of traits such as ornamental handicaps and male parental care, in which the trait is an honest costly signal of male quality. However, both of these explanations require the exogenous initial spread of female preferences before harmful male traits can evolve. Here I present a mechanism for the evolution of female mating preferences for harmful male traits that is based on the selfish evolutionary interests of sex chromosomes. I demonstrate that female-biased genetic elementssuch as the W and X sex chromosomeswill evolve mating preferences for males who display traits that reduce their fitness and/or that of their male offspring, 研究提出了一种基于性染色体的自私进化利益的机制, and Zahavis handicap principle。
与性别相关的偏好可以驱动诸如装饰性缺陷和雄性亲代照料等性状的进化,与w相关的偏好会导致几乎致命的男性特征被彻底固定,Pavitra Muralidhar证明,隶属于施普林格自然出版集团。
