Genetics If A B are sisters and each of them had a greatgra

Genetics: If A & B are sisters, and each of them had a great-grandchild, G & H, do G & H share < or > 1% of the same DNA?

Solution

The great-grandchild will have 12.5% of DNA from her grandmother.

So, both G and H will get 12.5% DNA from their grandmothers A and B.

So obviously both G and H will have a chance to share <1 or greater than 1% of the same DNA.
