I don't even get the expression "hopelessly hybridized". What do you mean by that? Anyway, diversity also comes from recombination, which is high in honeybee. Are you suggesting that the population of honeybees in USA lacks diversity and the only way to remedy that is to bring in stock from Europe? Because this is simply not supported by the literature which suggest a highly variable and diverse population. Which is certainly large enough to not be in a genetic bottleneck in any case.My point being, if most of our stocks are hopelessly hybridized, where exactly do we get this putative genetic diversity if not from some reproductively isolated stocks/ferals?
