Subject: [DNA] Variance Assessment of R:U106 DYS425Null Cluster
Date: Tue, 2 Feb 2010 20:04:02 -0000


A collection was made of 153 haplotypes of R:U106 with 67 Markers and STR DYS425=Null
The haplotypes were obtained from YSearch and other public databases.

The haplotypes were sorted by geographical location using the country of earliest ancestor and
where that failed, using the surname as an indicator of the country of earlier ancestors.

Two resources were used to identify the most likely nationality of the surnames; firstly the
International Genealogical Index ( IGI ) which has surname entries from European countries back to
the early 15th Century; secondly, the National Trust Names profiler, which uses the 1881 Census.

Haplotypes with repeated surnames were removed from the list.

The remaining 140 haplotypes were distributed as follows:-

England 53
Germany 24
Ireland 14
Scotland 12
Wales 9
Switzerland 7
France 6
Austria 4
Belgium 3
Denmark 3
Italy 2
Finland 1
Portugal 1
Poland 1



All haplotypes from mainland Europe were added together and compared with those of England


The 53 England and 51 Mainland Europe haplotypes were inserted in the " Generations 4 " spreadsheet
of Ken Nortdvedt.

This showed that Ga coalescence England = 102 generations
Gb coalescence Europe = 95 generations
GABw = 101 generations

On the face of it, this seems to suggest that the R:U106 Null425 RecLoH may have been in England
for about 150 years before it was in mainland Europe.


Any constructive comments would be gratefully received.
