Was written in pencil? (*lol*)...Most forms of dominant genetic traits will/should produce "visible hets"...this is the key determining factor that separates both "co-dominant & dominant" traits from recessive ones,is it not? visible results in the first subsequent generation moving outward from the hypothetical source is our first evidencial clue in any breeding trial...reliable visual distinction between hets & homozygotes doesn't negate the ability to reliably distinguish expressive recipients from non-gene carriers within the litters,at all...If we cannot find reliably determining criteria between hetero & homo after "umpteen" generations we might want to get out the eraser,and,do away with the "co-" prefix on that "birth certificate"???
