>>15498470hybrid vigour is a term from animal or plant breeding, where it's typical to hybridise two purebred (inbred) strains, to create a mix of desirable gene traits. This obviously doesn't apply to any outbreeding human population, which 99% of whites are. see pic related - certain people due to very small breeding populations or cousin marriage cultures would definitely benefit from outbreeding and get a hybrid vigour boost.
