DNA Marker Analysis
I have just completed an upgrade to the Marker Analysis I did last year. This new analysis now includes 4230 participants in 131 different surname projects.
The topics in this analysis are:
1) 12 Marker Duplications Across Surnames - 68% of the participants who match someone else on their 12-Marker test shared a 12 marker combination with someone of a different surname. All of the 131 surname projects had at least 1 12-Marker match with another aurname project.
2) 25 Marker Duplications Across Surnames - Just under 5% of the participants who match someone else on their 25-Marker test shared a 25 marker combination with someone of a different surname.
3) 12 for 12 Matches that Failed the 25-Marker Test - 20% of the participants who matched 12 for 12 with someone in their on surname group on the 12-marker test failed to match at least 23 for 25 on the 25-Marker test. Another 5.0% of the participants matched at least 23 for 25 on the 25-Marker test but had 3 or more total mutations.
4) Distribution of Values - If you take the most frequent value for each marker you get:
13-24-14-11-11-14-12-12-12-13-13-29-17-09-10-11-11-25-15-19-29-15-15-17-17.
Only one participant in the group studied matches this 25 marker string. 125 participants matched on the 12 marker string. These 125 matches represent 54 different surname groups.
The results of this study can be found at
None of the participants or surname groups used in the study are identified.
