No intention of even trying to make you look dense  Its just that I am a biologist so, the way you wrote out certain things sort of, how shall I put this, didn't quite look right to me. Most people don't get this stuff at al, so you are doing quite well  An, I might have frased things a bit differently in the last post, just put it down to me being a foreigner |

Ron, how would I express something like a Bumblebee (pastel / spider) bred to an albino?

Lets see, if Bumblebee is Pastel+Spider, both dominant (or Co-dom, depends of there are supers), but anyway lets say PpSsAA and albino would be ppssaa
So
psa psa psa psa psa psa psa psa
PSA PpsSAa PpsSAa PpsSAa PpsSAa PpsSAa PpsSAa PpsSAa PpsSAa
PSA PpsSAa PpsSAa PpsSAa PpsSAa PpsSAa PpsSAa PpsSAa PpsSAa
PsA PpssAa PpssAa PpssAa PpssAa PpssAa PpssAa PpssAa PpssAa
PsA PpssAa PpssAa PpssAa PpssAa PpssAa PpssAa PpssAa PpssAa
pSA ppSsAa ppSsAa ppSsAa ppSsAa ppSsAa ppSsAa ppSsAa ppSsAa
pSA ppSsAa ppSsAa ppSsAa ppSsAa ppSsAa ppSsAa ppSsAa ppSsAa
psA ppssAa ppssAa ppssAa ppssAa ppssAa ppssAa ppssAa ppssAa
psA ppssAa ppssAa ppssAa ppssAa ppssAa ppssAa ppssAa ppssAa
basically 25% PS or pastel spider, 25% pastel (Ps), 25% spider (pS) and 25% neither pastel not spider
all are het albino of course (Aa)
The above obviously depends on whether the pastel and spider genes are heterozygous or homozygous.
BTW Co-dominant means that both alles are just as strong, i.e. the het is a blend of the mutant gene + the original, or an "in between" form. So, if het spider looks the same as a homozygous spider then it is a domimant mutation, not co-dom. For a co-dom you would expect the homozygous form to show a different (stronger) phenotype then the heterozygous form. I thought spider and superspider look the same, so dominant, and not sure about pastels |
