New article in PNAS

We have a new paper in press at the Proceedings of the National Academy of Sciences, USA. It is the first study to characterize a promoter microsatellite for the oxytocin receptor gene (Oxtr), and demonstrates how the length of these regulatory-region associated microsatellites corresponds to the level of gene expression, with corresponding fitness effects. Importantly, this study is also one of the first in vertebrates to characterize sexually antagonistic genetic loci – Oxtr and Avpr1a – which have different fitness optima in males and females. It is an open access article, viewable by anyone here.
