In addition to the Byrnes 227877 that Susan is describing, we had another Byrne Project Chromo2 test returned today. Byrne 236891 is S660. That makes four separate branches below M222 for the four so far tested (S7814, S603, S660, and S658/PF1160). I can hardly wait for the remaining three. The person who handles 236891's account has sent his raw data to Mike. Paul
