Mrnjavac et al. reevaluate arguments against Muller's hypothesis, and find that they do not conclusively exclude a role for sheltering in sex chromosome evolution.

An Extension of Muller's Sheltering Hypothesis for the Evolution of Sex Chromosome Gene Content
Abstract. The first influential hypothesis for sex chromosome evolution was proposed in 1914 by H. J. Muller, who argued that once recombination was suppre

Over a 100 years ago Hermann Muller hypothesized that Y chromosome degenerates because it is sheltered from selection by the X chromosome. Sheltering hypothesis was dismissed in the following years. Here we re-evaluate it. www.biorxiv.org/content/10.1...

New article! We show signatures of reduced efficiency of selection on the young Z region in Schistosoma japonicum. Together with other studies on young sex chromosomes, our results suggest that young and old sex-linked regions show distinct evolutionary patterns. doi.org/10.1093/gbe/...
