After dinner tonight we were all sitting around the table when Heidi's dad pulled a screenshot up on his phone. It was her brother's DNA profile. I glanced at it politely, but without much interest; after all, I had spent some time studying Heidi's DNA, so I really didn't expect any surprises.
Oh, me. It turns out I don't really know everything. As often as I learn that lesson, clearly it hasn't quite sunk in yet. Sibling DNA is not identical, and ethnic markers can be very, very different. For example, in the case of Heidi and Mark, she's 46% British Isles, and he's only 2%.
Holy cow! Maybe there is some American Indian in our past that I just missed out on! DNA tests all around!
