> Since type 0 blood is the Universal blood type and used in transfusions when a patients blood type is not known I don't think I believe this. Wouldn't type 0 be the type blood of the most people? Phillipa
Whether an allele is dominant or not is a separate issue from how frequent the allele is in the population. Huntington's is caused by a rare (dominant) allele affecting 1 in 20,000. With blood type O is the wild type / ancestral form and A and B are mutations from the O allele that arose in the last 20,000 years. While A and B are dominant over O (and co-dominant with each other) they are still relatively infrequent.
At least that is what the internet leads me to believe...
