- Part 1 of a 3-part introduction series to Y-DNA for genealogists. This first video focuses on "Why?" use Y-DNA for genealogy - what benefits does it offer and why should genealogists consider using Y-DNA as part of their research? (CLICK TO READ MORE)

Wish I'd found your videos sooner. Excellent resource and very well presented. Thank you!
Fabulous thanks David. Great clarity visually and verbally. I have just ordered your book. As you say, it is exciting to contemplate what the next 10 years will bring.
Listened/watched the three Y-DNA videos all in a row. Very helpful. So much to learn... 👍
Nicely done. I’ve learned something here. Great clarity and a good first step for me. Just ordered the Big Y, awaiting the kit to arrive. Joined a group.
Awesome info without noise and great teacher!
Fantastic video, very helpful! Thanks so much.
Thanks so much. Very informative. Charts help explain it a great deal to me. I say I know enough about DNA to get into trouble ;-) According to the Chandler Family Association DNA Project I am part of Group 7A, but, my surname is not Chandler. So they say there is an Non-Paternal Event (NPE). No way to determine when and with who or where. Documentation and Autosomal matches (at Ancestry DNA) very much confirm lineage back to documented great-great grandfather in Alabama. Further back I can't say. Probably back on some branch to John Chandler the Emigrant (b. London 1600) but it could have been to an unknown first cousin or unknown brother of John who also emigrated to the Virginia colonies in the 1600s. But they accept me as part of Group 7A in their Y-chromosome DNA Project.
Oi. Um e meio por cento no DNA autossômico é há quantos séculos? e dois por cento é há quantos séculos?
Com o DNA autossômico, você poderia ver essas porcentagens com alguém que compartilha um ancestral comum entre 2 e 7 gerações atrás. O DNA autossômico não se mistura em quantidades exatas, então a gama de relações possíveis é maior com pequenas porcentagens.
My niece just had my brother do this. The results are back but we're confused. I've thought about doing the female line but my mom's side is fairly well known to us. My dad's father's side is the one we know little about.
Hi! If you're looking for answers within a close number of generations, what matches you have is what probably matters the most.
See if there is a surname project for your surname (just google ' DNA project' and look for anything under the 'familytreedna' websites); if you join that the administrators (who are all volunteers) can usually help you make sense of your matches and can even put you into a group that you're closely related to.
Or if you're on Facebook, look for the "Genetic Genealogy Tips & Techniques" group which has a lot of members and is a good place to get tips.
@@DaveVance01 Thank you.
Are you saying the haplogroups are a myth? Specifically regarding people of sub-saharan African descent
Haplogroups are definitely not a myth; they represent ancestors, usually very distant ones, along our patrilineal (male-only) ancestry. The modern names they are assigned don't mean anything to our ancestry of course but the haplogroups themselves are very real.
Note that your Y-DNA line is only a very small part of your ancestry; going back only 10 generations it is already only 1 out of 1,024 of your ancestors so your haplogroup does not correspond at all to your overall ethnicity and usually your Y-DNA origin won't show up at all in your ethnicity percentages unless many of your other ancestral lines are also from the same origin.
Thanks Dave. I had commented before the video ended, in the beginning when you mentioned the myths. I was confused about how you presented it. Because you stated it won't tell you where it likely originated. Many descendants of slavery have turned to Y-DNA for assistance in genealogy.On a side... I have zero matches at the 37 marker level . Unfortunate. I did have one match at the 12 marker level. Showing a distance of 1. Am I correct in assuming the common ancestor is probably very far back? thank you very much for this series. I enjoyed it
