These data are from experiments performed by pairing fish of two possible ecotypes from either the same lake, or from two different lakes: 0.6 Same lake Different lakes 0.5- Probability of spawning 0.4- 0.3 0.2- 0.1- 0 Limnetic Limnetic x Benthic Benthiq, X Limnetic Benthic The "Limnetic x Benthic crosses show tha diferent ecotypes show pre-ryotic isolation if they evolved in sympatry but not they evolved in allopatry ecotypes from the same lake represent different species O regardless of genetic similarity, fish of the same ecotype show a precisation O regardless of genetic similarity show site-assortative mating different ecotypes show postati isolation regardless of whether they evolved symetrically or alopatically
