Even at only 12 markers there are cases where father and son are a genetic distance of one! If a marker mutates once every 1,000 years, do you know when the last mutation occurred in your line? Maybe it was 1,001 years ago. Also remember mutation rates are the average rate for 1,000s of lines, not yours.

I wondered if an ancestor say 300 years ago who was malnourished or exposed to severe environmental hazards (e.g. mercury laden hats) had a different rate of mutation than one brought up in idyllic circumstances?
