...reproduce itself. Two species are marked as distinct if mixed members either will not mate or cannot produce fertile male and female offspring. Thus the horse and the donkey are separate species because their issue, the mule, is always sterile. In the case of the fruit flies, the Llanos strain was capable of producing fertile young with other strains in 1958, but when they were remated later, the males of the isolated group could not sire fertile sons with any females except those of their own strain...
