OK, folks, highschool genetics is all I got, so simple terms would be nice! lol. I know that if you breed blue to blue, you will get splash, black, and some blue. This would lead me to believe that the allele for blue is codominant with the one for black. So a splash would have B (black) and B1 (blue) alleles, black would have BB, and blue would have B1B1. Once again, a little rusty on the genetics... but I am really curious! Thanks in advance!
