Thanks Bill, for the detail and links. I' not relying on any of the information from the altered parameters, but learning more is always a good thing. A good example of how we carry genetic material from our parents and theirs before them is a recent relation who found me. She sent me a message through 23andMe because when her results came back, I was her second closest match. The first was a cousin on her maternal side whom she already knew.
What she didn't know was who her father was. Her mother had passed years before and she didn't even have a first name. So through a lot of searching on my Ancestry tree, which is far more developed than what I've accomplished here yet, we were able to narrow it down to my paternal line. She did another test through Ancestry so we had more people available to triangulate. In the end, we found her father. The distance in our connection is what I find so fascinating. As it turns out, her great-great-grandfather was the brother of my grandfather. The ages are part of what confused us. I'm 19 years older than her so we thought her father's generation would be no more than one generation greater than mine, but obviously, that wasn't the case. Still, we share 2.04% of our DNA and 152cM across 6 segments.
