Sexually antagonistic genes are beneficial to members of one sex, but costly to the other. They are of significance both to the coevolution between the sexes and the evolution of the sex chromosomes. We will measure the sexually antagonistic effects of genes that make male guppies sexually attractive. We will then study how these genes, and the process of sexual selection that favours them influence the process of recombination between the X and Y chromosomes.

性对抗基因对一种性别的成员有益，但对另一种性别的成员则代价高昂。它们对两性的共同进化和性染色体的进化都具有重要意义。我们将测量使雄性孔雀鱼具有性吸引力的基因的性对抗效应。然后，我们将研究这些基因以及有利于它们的性选择过程如何影响X染色体和Y染色体之间的重组过程。
