I checked out the milk forum too, and the bottom line is that some genes (many genes) are not explainable using mendelian genetics alone. In fact many genes are not explainable through breeding trials period. Unless you understand the molecular mechanism it will just seem random.



While this is frustrating to breeders, especially since some folks who can make a punnet square think that they know all there is to know about inheritance, it is the truth. Genes have many weird mechanisms for changing phenotype, and new ones are found all the time. In fact reptiles are probably the least studied group of all animals when it comes to genetics. We know lots about viruses, bacteria, mice, rats, humans, and african clawed frogs...but almost zilch about reptiles and birds.



It sounds to me like you are making a lot of assumptions about this trait. Where did the whole 66% of all hypos being het extreme come from? Why 66%?
