Abstract excerpt

In populations of fish species, polygenic sex determination (PSD) can evolve in different directions, depending on environmental fluctuations and migration rates. The European seabass provides an interesting model to explore such evolutionary phenomena, because it exhibits a PSD, mainly driven by temperature and has three genetically differentiated populations evolving from a common PSD ancestor. We produced...
