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 "It is more likely that the mutation arose spontaneously because Victoria's father was over 50 at the time of her conception and haemophilia arises more frequently in the children of older fathers.". Is that enough to answer the question?
Answer: yes
