I was watching Terminator: The Sara Connors Chronicles last night and it was said that Sara's blood type was O- and John's AB-. Er, don't science fiction script writers check their basic genetics! Somebody with blood type O can't have an AB child! Well they can if they're a chimera or have two copies of the very rare h-ve gene but this is highly unusual! They could have made John and his uncle both B- (which is still fairly rare) and it would have been possible without invoking anything weird!
What is so difficult about genetics that so many people just seem to have soom weird blind spot about it?
