You could have a grandparent who was 100% native american. Your parent from that branch would be close to 50% native DNA but there is no guarantee that you would have any native american DNA, you might and might not, you could have sibling with a large percentage while you have little or none. Before I got the test I mistakenly believed the DNA was split evenly from you ancestors, not true, its pretty random.
