CONT

At least one Queen Charlotte lake contains a pair of sympatric (living together in the same habitat) and distinctive populations, which behave like different species in that they do not interbreed although differing by less than 1% sequence divergence in restriction endonucleases. Similar conclusions can be drawn from earlier work by McPhail (1984) on sticklebacks on Texada Island and Enos Lake, British Columbia Two populations of rainbow smelt, Osmerus mordax, in Utopia Lake, New Brunswick, also do not interbreed and had sequence divergences of about 1.2%.

OBS

sympatrique : qui habite la même région qu'une autre race ou une autre espèce.
