Everybody is inbred, it’s a matter of degrees!
But especially if you’re from the south of USA
What am I looking at here?
You share half your DNA with each parent. Sounds right.
You share less than a quarter with your grandparents. Sounds right (some luck involved on which DNA was passed two generations).
Your cousin shares 10%. Since your parent’s siblings should share about 25% of their DNA, and their kids would be half that, then 10% for a first cousin seems right.
What am I missing? I’m not familiar with their process so may have misunderstood what’s being shown.
Edit: oh, is it saying you share 20% with each grandmother, or is it the same 20%? The same grandmother? Your parent’s had the same mother?
What am I looking at here?
“Grandmother, Both sides, 21.99% DNA shared”
Each entry in this list has submitted their DNA to 23andme, and it detects enough overlap in the sample from this grandparent and both parents that it can’t tell which side to place them on.
Thanks! I’m not familiar with their system so didn’t realise this was how it worked.
For context, the weird part is “Grandmother, Both Sides”. Given that mother and father are qualified as “Mother’s Side” and “Father’s Side”, respectively, “Both Sides” seems to imply that this same one person appears on both sides of the tree, I.E. Mother and Father share a mother.
No idea if this is actually what 23andMe is trying to say, or if it’s just really poorly worded.
Don’t feel bad. Ancestry gave me that thing for famous people in my tree. Turns out, I’m related to several of them on both sides. Your grandma mentioned is probably grandma on one side and great grand aunt on another or something.
… Or your parents are secretly flowers in the attic-ing you, in which case do not allow yourself to be locked in the attic. Always carry your cell to call the police.
