That was interesting but as we say here in USA I want the most bang for my bucks and my family submitted swabs for the tests I had mentioned there was no info re "mutation" factor but that Father to Son, Mother to Daughter was an unbroken line. I found out that mutations do occur and that break sends out a new line which as far as I know the before/after gives little retrievable info. Things seem to be moving ahead at fast speed and I agree the more markers the better the test. Good Luck if you go ahead you may turn out to be one of those with unbroken lines.
