Hi list, My aunt matches her fifth cousin on chr 17 as follows: 25354798 30027010 7.84 1249 33868089 47167537 12.67 2900 Is it likely these 2 sections are from the same ancestor? How close do segments have to be to make it likely they are from the same ancestor? What accounts for a section being "broken up" in this way? What's a good layman's way of understanding "how big is big" when talking about these kinds of break up on a chromosome? Thank you. Barton
