🌺 New preprint out with John Pannell and @charlesmullon.bsky.social ! 🌺

We show that selection broadly favours a form of plasticity for the selfing rate where individuals adjust their mating behaviour to their condition — their overall vitality owing to their genetic background and environment. ⤵️

Will be presenting this work today at #eseb2025 poster P02.184, come by if interested about whether we should expect recombination suppression on sex chromosomes should evolve through modifiers on the X or the Y

New paper out with Thomas Brazier, Denis Roze and Sylvain Glémin!

The joint evolution of separate sexes and sexual dimorphism Abstract. Dioecious plants are frequently sexually dimorphic. Such dimorphism, which reflects responses to selection acting in opposite directions for male

1/7 Very happy to share our latest paper on the joint evolution of separate sexes and sexual dimorphism in @jevbio.bsky.social, led by @thomaslesaffre.bsky.social and in collaboration with John Pannell at @dee-unil.bsky.social

The maintenance of genetic polymorphism underlying sexually antagonistic traits Abstract. Selection often favors different trait values in males and females, leading to genetic conflicts between the sexes when traits have a shared gene

1/7 Sexual antagonism arises when males and females face different selection pressures for a trait influenced by shared genes. This is thought to drive balancing selection and maintain genetic polymorphism. We challenge this view in our recent paper :
