"Evidence that genetic compatibility underpins female mate choice in a " by Phillip G. Byrne, J. Scott Keogh et al.
Mate choice for genetic benefits remains controversial, largely because few studies have estimated the relative contributions of additive and non-additive sources of genetic variation to offspring fitness. Moreover, there remains a deficit of these estimates for species where female-mate preferences have been quantified in the wild, especially species characterized by monandry or monogamy. Here, we use artificial fertilization techniques combined with a cross-classified breeding design to simultaneously test for “good genes” and “compatible genes” benefits of mate choice in the monandr...
