Evolutionary biologist interested sexual selection, sexual conflict and mating systems.
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!
Two research teams from @cnrs.fr @sbroscoff.bsky.social carried a comparative analysis in flowering plants that supports the prediction that inbreeding, such as self-fertilization, selects for higher recombination rates:

Mating system and the evolution of recombination rates in seed plants
Abstract. Meiotic recombination is a central mechanism underlying sexual reproduction among eukaryotes. In many species, the recombination rate is strongly

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 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 :

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
