Yes, I am still trying to understand my Y-DNA results. And it has been sometime since I have even touched my data and information. My current and tested Haplogroup is R-L23 (R1b1a2a).
Here’s a quick rundown. According to Max Blankfeld of Family Tree DNA, there are 23 pairs of chromosomes: 22 pairs are what we call the autosomal or the recombining DNA. The 23rd pair is the sex gene. Paternity tests use the autosomal. Those are passed from both mother and father and "mixed" into the child, whether male or female. This mixture generates a new set of 22 pairs. This is the part of the DNA that a paternity test company uses.
The 23rd and final pair, the sex gene, is transmitted to the children. A male child receives X-Y, which is the father's Y-DNA and the mother's mtDNA, while a female child receive X-X, which means only the mtDNA from the mother. The Y received by the male son, is passed on to his son. This son receives his mother's mtDNA, not the grandmother's. So, the Y-DNA goes down the line while the mtDNA does not, and the autosomal continues to be mixed as it progresses down and through the generations...
A male child, and that includes me, receives my Y-DNA and that is the data that is revealed from my Y-sex gene, the part of me that I get from my father, Frederick Kenneth Lloyd Smith. This would mean that all the male Smiths, including the Lloyd Smiths, the Malin Smiths, the Landreth Smiths, et al, who are descended from great-great-great-grandfather James Smith all received the same Y-DNA.
The confirmed Haplogroup is R-L23; also written as R1b1a2a.
As you can see from the two ISOGG, 2010 and 2011, our R-L23 is the “Most common European R1b”.
There is a ton of work to go through and the study of genetics continues. Because my Smith Y-DNA is of the “most common European R1b”, and apart from having the most common name in the English language, I am continuing to investigate and delve into the testing. I have had some success and have been able to match 111 markers through Family Tree DNA to three/four other surnames: Ware; High/Robinson; and Seymour/Seymer.
I will carry on digging, and I mean drilling down, as tests continue to be added. Two outstanding tests are currently slated to be completed – CTS7822 and F2863. Theirs is still one hell of a lot for me to learn. Also I need to restart my search and research for the origins of our ggg-grandfather James Smith.
