X-DNA View For Fan Chart Tree

Charlie Bedwell said: X-DNA Genetic Fan Chart Tree View
Hi all - thank you for what you do!
A suggestion as I learned about different views for seeing one's family tree. Since familysearch already has the family trees, including the Fan Chart view, have you considered adding a layer/color coding to the Fan Chart view that would allow users to see an automated X-DNA genetic tree view from each Fan Chart tree? That would be a very nice addition, especially to those of us trying to narrow down the possible familial connections for different DNA matches.
What do you think?

Thank you!

Without extensive testing of a large number of the SNPs, actually identifying the Y-DNA haplogroup may not be possible. I had to add additional SNPs to my Y-DNA results to come up with the actual haplogroup. Of the companies that produce haplogroups, only FamilyTreeDNA (not associated with the FamilyTree family tree management program) was able to reliably produce the haplogroup, even between generations.

23andMe's haplogroup results were inconsistent between me and my son.

And if a testing company does not produce haplogroup results (such as Ancestry), then the admixture or autosomal DNA is highly dependent upon how the company interprets the results of the test. And when it comes to autosomal DNA, it does not hold for much beyond the third and fourth generations (the resulting sample is too small to be reliable).

Finally, Y-DNA follows only the paternal line -- son to father to father to father to father. mtDNA follows only the direct maternal line - son or daughter to mother to mother to mother, and so on. In most cases, the surname for mtDNA haplogroups changes with each generation.

Tom Huber said: By the way, I was very disappointed when I realized that a lot of hype has been applied to genealogical DNA testing. It took my some exploring before I found out why my son's Y-DNA haplogroup and my haplogroup did not match, even though both were initially provided by 23andMe.
