interested in the information you have that some scientists think a marker

I tried to answer your question off-list but your system kicked my message
back as spam. Following is what I wrote. Maybe others here will find it of
interest also.
=====================
When DNA changes, it always changes in one person. Then that change is
generally what gets passed on to their children. (Unless it changes back. Rare
but can happen.)

It is much like the changing of a last name. Generally, when a person
changes their last name, it is the new name that is passed on to their children.
I hope this helps.
