Paternal Line – Tales from the Genome


Joanne, it’s really, really exciting to actually look at my paternal line and see sort of how far back in time and, and geography we can go with this. But, if you don’t have a Y chromosome then how could you ever look at your paternal lineage?>>Yeah. And many women are interested in exactly that same thing. Even though we don’t have Y chromosomes. So, but there is a way to trace your paternal line even if you don’t have a y chromosome. And that is to find someone who has your father’s y chromosome. my father passed away years ago so he wasn’t available for testing. but my uncle kindly agreed to get tested and so I was able to learn about my paternal line through him. And other possibilities if I had had a brother. If my paternal grandfather had been alive. So there are a number of relatives who can help a woman trace her paternal line.>>Okay, Matt. So, we see here that you and your dad have a, a paternal lineage called I1.>>Mm hm.>>actually, I1 star. And we see, from the map, that it’s very, very frequent in Northern Europe, particularly in Scandinavia. I don’t know if you were aware of any Scandinavian ancestry on your dad’s side. But that’s, this is suggesting that if you go far enough back on your dad’s side. you might find that you have an ancestor who’s, lives in Scandinavia.>>Now this fits with the autosomal ancestry pattern that we saw for me, right, where it said I had a strong Northern European descent.>>That’s right. Yes, yes, yes. So this is just. Reinforcing that information that we see.>>I see, and it says that over here that age is 28,000 years. What does that mean exactly?>>So this lineage like all the the haplogroups are defined by a particular mutation that happened, you know, a long time ago. And in this case, 28,000 years ago a mutation happened on the y chromosome. And it’s the defining, and then everybody who inherited that particular y chromosone also inherited that mutation. And so, the last 28,000 years men and their sons have carried that particular mutation and you are part of kind of that clan.>>I see.>>Of, of males with this particular lineage.>>So this means that, in this region here. Somewhere in this region is where that mutation happened.>>It’s, well.>>About 28,000 years ago?>>We don’t know for sure where it happened. But because it’s most frequent in this general region now.>>I see.>>We, We speculate that it was probably in that, in that general area. You know, very far North in Europe.>>Now, let’s take a look, at actually. Let’s go back to Roy.>>Yes. King.>>Roy King and his father, Roy King, Sr, both have a lineage that is fairly common in in Jewish men. and that fits with Roy’s understanding that his father’s father was Jewish. So, we’re really seeing his grandfather right there in the DNA of the y chromosome. So to go a little deeper let’s click on the history tab and move away from the map. And this is an overall, you know, story about the, the history of this lineage J2. and and it mentions the, the branches of this J2 haplogroup spreading with the Jewish diaspora from the Middle East across Europe. so this is just what is, and this, all this information comes from studies of people who currently carry the J2 lineage around the world. And so many scientists have conducted studies and they publish papers and then this story is drawn from those publications.
