I will probably regret even getting involved in this but your initial nomenclature on your spreadsheet isn't correctly set up regardless of what theories you have of how the genes work, because if Normal is AA, then what is Aa? You say Normal het Aa....het for what? You would have to have an "aa" that is homozygous for the recessive trait that you are denoting with the "a".If you intended for this to be het axanthic then the homozygous axanthic would be "aa" not BB. Also capital letters typically describe the dominant trait and lowercase describe a recessive trait? Your "Axanthic BB" denotes the phenotype axanthic as a homozygous dominant genotype? Your punnet square skills need some work grasshopper.
