What rate of native american am I?

Question

My great-great grandmother is full blood native american.

What would that make me?

Answer 1

The other answer is technically correct, but I believe you are looking for your great-great-grandmother's influence on you.  You are 1/16 Native American!

1 parent = 1/2

1 grandparent = 1/4

1 great grandparent = 1/8

1 great great grandparent = 1/16

Answer 2

If your great-grandmother was full blood native American, and assuming no one else in your family is any part native American, then you would be 1/8 (one-eighth) Native American!
