Many invasive plants hybridize with other species. Hybridization can potentially impact the reproductive rate of the invaded population, or it can lead to replacement of native genotypes by hybrid genotypes (genetic assimilation). This talk explores conditions for these processes by focusing on two key questions - the rate of hybrid formation and the fitness of hybrids - in model systems of hybridization between natives and between exotics and natives.
