Speaker: Simon Martin (University of Edinburgh)

Vertically inherited endosymbionts can dramatically alter the biology and evolution of their hosts. Simon will describe how an investigation into an unexpectedly polymorphic butterfly population uncovered a case of hitchhiking between a male killing endosymbiont and a colour patterning neo-sex chromosome. Simon will show how genome sequencing has revealed the identity of the male killer and the captured chromosome, as well as the timing of these events. Finally, Simon will discuss the consequences for the butterfly both in terms of population genetics and sex chromosome evolution.
