It was one of those fast mutations that happened between the birth of the older brother and the younger brother. The rest of the 37 markers are exact. I can't remember if it is the Wells group or the Carter group, does anyone else remember this? Kathy Wells Kathy, This occurred in W037 branch W328 at marker DYS458. #391 is the older brother and #315 is the younger one. The mutation occurred in the older brother, but not in the younger one.
