一妻多夫在自然界中广泛存在，对两性异形和性冲突的进化有重要的影响。虽然一妻多夫制的许多表型后果已经阐明，我们对一妻多夫制和交配系统对基因组的影响的理解还处于起步阶段。一妻多夫制会加剧对性特征的选择，产生更激烈的性冲突。这对序列进化有影响，但也对性别偏见的基因表达有影响，性别偏见的基因表达是交配系统、性别特异性选择和两性异形进化之间的联系。我们讨论了这一点，以及性冲突理论和基因表达模式的显着融合，同时也对转录模式，交配系统和性冲突进行了预测。基因表达是基因型-表型链中的关键环节，尽管处于早期阶段，但了解性选择-转录关系将为这种关键关联提供重要见解。
Polyandry is widespread in nature, and has important evolutionary consequences for the evolution of sexual dimorphism and sexual conflict. Although many of the phenotypic consequences of polyandry have been elucidated, our understanding of the impacts of polyandry and mating systems on the genome is in its infancy. Polyandry can intensify selection on sexual characters and generate more intense sexual conflict. This has consequences for sequence evolution, but also for sex-biased gene expression, which acts as a link between mating systems, sex-specific selection and the evolution of sexual dimorphism. We discuss this and the remarkable confluence of sexual-conflict theory and patterns of gene expression, while also making predictions about transcription patterns, mating systems and sexual conflict. Gene expression is a key link in the genotype–phenotype chain, and although in its early stages, understanding the sexual selection–transcription relationship will provide significant insights into this critical association.
