Did you grow up knowing about the terms centimorgans, DNA segments, autosomal, and genetic genealogy? Me neither. I never had them on a spelling test. I never read about them in biology class. Well, maybe I did. Biology was never my best subject. These days, it seems that I hear these words at least once a day. While the terminology has become commonplace, I'm still working on mastering what they each mean.
Today, while reviewing my new DNA matches at MyHeritage, I was thrilled to see, for the first time ever, a genetic genealogy phrase I easily understood. I didn't need to click on a "what does this mean?" link or a question mark icon. For those who understand centimorgans and exactly how many of them are equivalent to a predicted relationship without looking up the chart - I'm happy for them. But for me, for the first time, I understand how much DNA I inherited from Dad.
And from his Dad:
And from Mom's father:
And from Mom's mother:
My DNA test results are up at to Ancestry, GEDMatch, and MyHeritage. While all three have the technical cM figures, finally someone has translated those figures into a down-to-earth phrase I understand - Shared DNA %. In the past, I've known that I inherited 3,559 cM from Dad, but now I get what that means - I inherited 49.1% of Dad's DNA! Which probably means I inherited 50.9% of Mom's. That will be fun to bring that up at our next family reunion. I've learned from DNA webinars that we inherit approximately 50% from each parent, 25% from each grandparent, and so on. It's fun to see that I have 28% from Grandpa Larsen but only 18.1% from Grandma Larsen.
One of the challenges I have as a neophyte genetic genealogist is the terminology. So, even though they are new to the DNA world, thank you MyHeritage.com for making this part of DNA a little easier to understand.
