On the 11th, I put together a Facebook group for Y-DNA, then I held off on pushing it live. I was not 100% sure what direction I wanted it to take. While waiting, I have discovered two things. First, the genetic genealogy community is ready to embrace NexGen type Y-DNA testing like Family Tree DNA's Big Y. Second, more than ever, new and even experienced community members are confused about what Y-DNA testing can do for their genealogy and the meaning of the jargon.
What is a SNP? What is an STR? How are Y-Trees built? Today, I am writing about the basics of Y-DNA test results.
