Answer 1

Hereditary gene mutations are there effectively from the creation of the egg or sperm. A parent that passes a mutation on to their child has almost certainly had that mutation since conception, so it doesn’t matter when a woman creates that egg or man creates that sperm; they have the mutation for life.
