DESCRIPTION:Dr. Zena Hadjivasiliou (UNIGE)\nWe are delighted to announce t
 hat the next seminar of TheBioNet will take place on Wednesday\, 12 May\, 
 16:00-17:00 via Zoom\n\nSpeaker: Dr. Zena Hadjivasiliou (UNIGE)\nTitle: 
 The evolution of sexual differentiation\n\nThe two partners required for s
 exual reproduction are rarely the same. This pattern extends to species th
 at lack sexual dimorphism yet possess self-incompatible gametes determined
  at mating-type regions of suppressed recombination\, likely precursors of
  sex chromosomes. In this seminar\, Zena Hadjivasiliou will argue that th
 e interactions between cells required for sexual fusion are optimized when
  cells communicate asymmetrically. She will show that under selection for 
 robust signaling between mating cells and fast mating\, cells that belong 
 to different mating type groups evolve. She will discuss how these finding
 s can help explain other key features of the sexual lives of unicellular o
 rganisms like the number of mating types\, the ability of some cells to sw
 itch their mating type identity stochastically and the emergence of sex ch
 romosomes.\n-------------------------------------------------------\n\nYou

 us\nThe aim of TheBioNet is to build a community of researchers working on
  diverse topics in mathematical and theoretical biology in Western Switzer
 land. Every semester we are holding seminars every two weeks where we have
  invited researchers from Western Switzerland working in theoretical and m
 athematical biology.\n
