it would be much easier to follow genetics if it is graphed or charted out.
by the way, the creators of the Pigeon blood where accused of creating them in a lab.
Blue diamonds took many generations to create, in fact many of the first blue diamonds actually had the vertical bars burned off with UV or so the story goes.
gregor mendal used a very simplistic method of proving his theory of genetics. if you are working with developing one or two characteristics a simple chart will work for you.
by the way exceptional fish have always come out of average fish. by exceptional of course it has nothing to do with other than tweaking the body shape, hi-body, hi-fin, vail fins, round head, color etc. to something we perceive as a superior fish.
remember the superior fish is the brown discus, it is the strongest most fertile, the strongest immune system, and the longest lived.
have fun
