This is the functional description of speciation. A state of affairs in which two genetically related organisms are incapable of successful breeding with each other. The tomatoes, in this instance, are sufficiently genetically similar, though not identical, to produce offspring. When genetically dissimilar but reproductively compatible organisms mate, the process of evolutionary change which necessarily follows is called hybridization. Let's suppose that...for whatever reason, the hybrid offspring of our two dirt apple parents is wildly successful. Where would the next generation of dirt apples get their genetic material from?
The definition of a species is a bit blurry, and there's a few methods used to demarcate them, but yes, the biological method looks at reproductive isolation as a marker.
As with your other test, I'll concede that genetic information alone can determine if two species are reproductive isolated, only if you provide me with the appropriate research. Otherwise I can't.
