European Y-DNA
  Detail Comparison by Country



Detail Comparison analysis will compare your Y-DNA results against individuals in two countries to find those that may match your genetic tree. This is used with Time to Most Recent Common Ancestor to help determine the place and time for your ancestors, typically from 500 to 1500 years ago. Individual results may vary.

An example of its use to compare England and France in order to find Norman ancestry:

Requirements:

The requirements for ordering the product are that you must have tested for Y-DNA, preferrably with Family Tree DNA. The data should at least be in Y-Search format. The more markers tested, the better resolution of the results. Results from less than 37 markers are not reliable for the time frames studied. At least 67 Short Tandem Repeat (STR) markers are recommended.


Restrictions:

Only the direct male line is presented (Branching per location is not shown). Typical results are from 500 AD to 1500 AD (500 to 1000 years ago). Individual results may vary.
The analysis requires that the customer has been tested for Y-DNA. Format of the data should be in Family Tree DNA or Y-Search format. Currently only available for haplotype groups I1. R1b migration studies are expected to be available in July, 2010. The results are dependant upon available data.

Processing can take several weeks for some types of data.

At the present time, the analysis is available to those of European ancestry. Not available for comparison within the Americas. For other areas, please inquire about availability of the data.

For European Country comparison, if insufficient data exists, your money will be
refunded.

If a DNA match is found to only one country, you will be contacted to choose another country. If no match is found for both countries
, your money will be refunded. For this analysis, you are considered to have a match if the Genetic Distance between you and the data is less than 30.

* Group rates are restricted to no more than 10 individuals who share a genetic distance within the following guidelines:

               37 markers with a genetic distance of no more than 6
               67 markers with a genetic distance of no more than 9
             111 markers with a genetic distance of no more than 12

  All individuals within a Group should be of the same haplotype group (all R1b, or all I1, etc.)

  Minimum of 37 markers. Anything less introduces significant error into the time line which results in unreliable results.
  At least 67 STR markers is recommended.

   The Country Detail Comparison analyzes two European countries for a TMRCA match to your Y-DNA results. This is a comparison between individuals in each country for your genetic match.
Please specify which two countries that you want to compare. For guidance on which countries to choose, I would suggest a Y-Search for your haplotype. Select the countries that have the closest genetic distance for this study.
