Is evidence that pairing with genetically similar mates maladaptive in a monogamous bird?
These findings provide evidence that breeders in a genetically monogamous species may avoid the fitness costs of reproducing with a genetically similar mate. In such species that lack the opportunity to obtain extra-pair fertilizations, mate choice may therefore be under high selective pressure.
The study shows high levels of interobserver and intraobserver agreement of the C-EOS scheme. The C-EOS scheme can be used as a reliable tool for classifying EOS patients for clinical communication and research.
