i believe that it all depends on the dog, i don' think it's right to categorize how they behave due to their sex. coco is a male, and yet he was sooo easy to train and is extremely smart. so to me it is all about that specific dog. i think that all yorkies can learn equally with the right amount and concept of training. boy or girl, i am sure you will find the baby that is right for you, it is just something that you feel when you see the pup, your instinct will lead you. good luck on your search!!!
