Title talk: Origins and consequences of unorthodox reproductive modes: Insights from stick insects
Abstract: Reproduction is a defining feature of life, yet the strategies organisms use to reproduce are remarkably diverse. While sexual reproduction is widespread, many species deviate from this norm, ranging from parthenogenesis, where populations consist entirely of females, to systems in which only the maternal or paternal genome is passed on to offspring. In my talk, I will explore how stick insects have evolved a variety of such unorthodox reproductive systems. Drawing on recent research from our team, I will highlight how these systems provide unique opportunities to investigate the roles of genetic conflict and sex-specific selection in evolution.
