user16651: In the past week or two I have seen a two posts asking questions related to information obtained from 23andMe or similar services.
I previously expressed that I thought it was not a good idea to answer these questions, as without a knowledge of the total genetic profile of the person, their family history, and the perspective of a genetics counselor, there was a risk that information provided could be unknowingly harmful.

Should questions related to results from genetics testing services be On-Topic or Off-Topic for Biology SE?

user18860: Questions about DNA testing from genetic genealogy services (23andMe, FamilyTreeDNA, etc.) are on-topic at Genealogy & Family History Stack Exchange.
Particularly the second question (What does it mean to have a Y-DNA Haplogroup "R-M512"?) would be better asked on Genealogy & Family History SE.
