Parapatric speciation hybrid zone
Did you know?
Primary hybrid zones occur where divergence is taking place between adjacent populations of a previously homogeneous species, possibly leading to parapatric speciation. As a population spreads across a contiguous area it may spread into an abruptly different environment. See more A hybrid zone exists where the ranges of two interbreeding species or diverged intraspecific lineages meet and cross-fertilize. Hybrid zones can form in situ due to the evolution of a new lineage but generally they result … See more Hybrid zones are thought to be less common in marine than terrestrial environments. However, blue mussel populations show extensive hybridisation worldwide and are a … See more Hybrid zones are areas where the hybrid offspring of two divergent taxa (species, subspecies or genetic "forms") are prevalent and there … See more • Genetic pollution • Hybrid swarm • Hybrid speciation See more Webv.11.20.09 2009 Revision/Edit 2010 ClassUse Version The Evolutionary Ecology of Weeds and Invasive Plants Jack Dekker Weed Biology Laboratory Agronomy Department Iowa State Univer
