TiP

I don't understand this TiP calculator. It says my son and I don't share a common ancestor until the 7th generation.

Ummm. That does seem odd. What is your genetic distance from him based on the most STRs you have both tested? Also, TiP just gives probabilities of how far back your common ancestor is, so I'm not sure what you mean by saying that it says you don't share a common ancestor until the 7th generation. What % do you have at each generation?

I echo this.

What is the resolution of your test? Y12,25,37,67,111?
