Johnston SE, J Gratten, C Berenos, JG Pilkington, TH Clutton-Brock, JM Pemberton, and J Slate. 2013. Life history trade-offs at a single locus maintain sexually selected genetic variation. Nature doi: 10.1038/nature12489.
We found that an allele conferring larger horns, Ho+, is associated with higher reproductive success, whereas a smaller horn allele, HoP, confers increased survival, resulting in a net effect of overdominance (that is, heterozygote advantage) for fitness at RXFP2.
Almbro M and LW Simmons. 2013. Sexual selection can remove an experimentally induced mutation load. Evolution doi: 10.1111/evo.12238.
Here we induced mutations in the dung beetle Onthophagus taurus using ionizing radiation, and tested the efficacy of sexual selection in their removal. … Two generations of sexual selection were sufficient to remove mutations that affected male strength, but not testes mass.
