IP is passed as an X-linked dominant trait and men will pass IP to all daughters but not to sons.
Hope this information is helpful.
Hi, from what I'm given to understand, IP happens when there are 3 X's attached to each other causing the mutation. I was tested for it when my daughter was born with it, but told that her father wouldn't new to be tested because males can't carry the nemo gene that causes IP. I hope it's some kind of help
