Mountain DNA Results

To date only men of Irish ancestry have submitted yDNA test results. Two clear clusters have emerged that are separated from each other by a genetic distance (GD) of 16 based on a comparison of 43 markers. This large genetic distance suggests that it is extremely unlikely that these two Mountain clusters share a common ancestor who lived since surnames were adopted in Ireland (ca. 1100).  The close matches within clusters means that it is likely (but not certain) that members of a cluster share a common ancestor who lived in the last 500 years.

Case #s 1 and 4 are known to be related

                       * unless otherwise indicated, haplogroups are predictions based on STR results

DNA makers highlighted in red (e.g. DYS385a) are known to be rapidly mutating markers. Cells in the table are colored to highlight differences between individuals and clusters.  For more information on genetic genealogy visit the International Society of Genetic Genealogy website: http://www.isogg.org/
