    3. I take it that my BCode of I2.0001010001 is contained within your I2.00*?

    3. George, Yes, you are in the STR branch I2.00*. Here, I am using the "*" (star) to mean a wildcard, with any values allowed to follow. All members (so far) of the branch I2.00* have P37.2+ and M423+, and so are I2a1b (ISOGG Feb 2012). This branch is mainly found in Eastern Europe, but see the map for the detailed frequency distribution.
