Thanks again Nancy,
I'm not a geneticist either, only a genealogist of over 25 years now, so this is Definitely not my area of knowledge, only by Observation and reading a lot over the last year and a half.
The solid markers that do not mutate except, supposedly, over long periods of time I am not so concerned with, its the ones the testing labs note as Rapid mutators.
Because each lab seems to use a different mathmatical equation to determine the rate of which these Rapid markers mutate, this also concerns me.
If I use Lab A. to do a ydna test and use Lab B. to do the same test will the end results be the same?
I think this may be why some labs do 37 marker tests and others use a 43 marker test and so on and so on.
Also I've noticed that some labs don't test on the Same Markers which is why when some folks go to Upload their results to places like Sorensen or YSearch they have use those Conversion Chart (entry forms) in order to get the proper results.This also makes me wonder.
Again, I am only interested in those men whose Results are showing multiple mismatches when they Know their Genealogy is Correct.Since the testing labs harp on "the paper trail" being the most important part of dispelling the myths of these rapid mutation mismatches, they are the folks I'm most interested in hearing from.
Also I've noticed that in the R1b, R1b1 etc. Group, because they are the Number One most frequent haplotype, their numbers are Very Close and have Many one and two step mutations between Same/Names.However in their cases, a True Common Ancestor could be many hundreds of years off between two families.
Our I1a group doesn't seem to have that much "sway" between the families but when they do, it appears to mean they are really off.
In our I1c group all of the Same/Surname, there have been two known non-paternity events that have showed up.There are also up to 3 step mutations between some of those lines, and yet they all have the Same known c1600's born many times grt. grandfather.Their lineages have all been proven by birth records and so forth back to that point but not any further beyond, so their common ancestor could still be hundreds of years Prior to the 1600's for all they know, but it was the ydna testing that brought it all together and really showed the proof of What Family Tree they really did belong in.
Thanks again.
