Bart Nieuwenhuis - Evolution of sexual asymmetry

Sexual reproduction generally occurs by the fusion of gametes that are different from each other, sperm and egg cell in animals, or in many microorganisms, cells of different mating types. But why are asymmetries during mating required, and why are gametes almost always limited to two types? In my group we study what drives the evolution of these asymmetries and their dynamics, as well as the consequences of having sexual asymmetries. We combine experimental, molecular and genomic approaches using fission yeast and the filamentous fungus Neurospora crassa as model organism, to address these questions.
