Okay, I hear what you are saying but why is it many wild rainbows I catch have not even a tinge of the red slash? While many others have varying degrees of a red to pinkish slash? I think it might be because the lesser marked rainbows are possibly the progeny of latter generations of an initial rainbow/cutthroat mating. Maybe as generations pass the gene causing the red slash becomes very diluted to the point of being very slight. Every true cutthroat I ever caught has a bright red slash.
it might be a good time to emphasize once again that just because a rainbow trout has a red or orange chin stripe does not mean it is a cut-bow or that it has cutthroat genes.
