Group 4 R1b>>L21>>DF49>BY2606

Group 4 has 16 participants with 12 different oldest ancestors.

Participant Anc04
Participant Anc04 is the hypothetical "common ancestor" of the participants in Group 4. Although it is impossible to actually know his DNA test results, it is possible to derive his most likely test results based on the results of his descendants (the participants). These results are shown below. Note than these results may change as more participants fall into Group 4 and more test results are available.

25 Marker Matches
All of the participants match on at least 22 of 25 markers.  Five participants (#3950, #5502, #8466, #94491, and #255954) match each other on all 25 markers. Participants #4178 and #55938 match each other on all 25 markers. All members of Group 4 match at least 23 for 25 with Anc04. The table below shows the number of mismatches each participant has with any other participant in the group:
