I want to know the answer to the following question:
What is a big factor on whether or not an offspring will spontaneously develop haemophilia?
All the background I'm provided with is that "There is no documentary evidence of a haemophiliac in connection with Victoria's mother, and as male carriers always suffer the disease, even if such a man had existed he would have been seriously ill.". Is that enough to answer the question?
Answer: no
