What fractions will add up to 3/64

I am 3/64 Native American and want to know how it added up to that.

just go back thru the generations; 3/64
3/32
3/16
3/8
3/4 blood degree. It comes about thru mixed marriages.

Yup like Roman said...there are unusual ways to arrive at this degree, but the most common scenario is that you descend from a tribal member who was enumerated at 3/4 degree (which is normally: fullblood + halfblood). Or, in this case we are probably about a GG-grandparent that was 3/4.

Ain't blood quantum fun???

1/32 + 1/64
1/64 + 1/64 + 1/64

Me, I'm 1/16th Cherokee and 1/16th Apache
So I'm 1/8th Native American. Both of my parents were 1/8th native American and so am I.

That would mean you are 4.6% native American.

Round it up, call it 5%

1/20 of you is native american
