Dna admixture

Dna admixture test results. 85% indo-european, 12% native american, 3% east asian. If all of the 12% na came from my mother side of the family, was my mother 25% na, grandmother 50% na and great grandmother 100% na providing each married a european......

Tks...

sounds like your mother was approx. 25% na, but her na could have come through her father...it doesn't just have to come through females.
