How can I confirm the significance of a low percentage of admixture?
There are two ways for you to confirm the value of this estimate: You may have access to historical records that leads you to confirm or refute the admixture. For example, if your records suggest that you have a grandparent of East Asian heritage and you register with the test as of 5% East Asian, the two observations combined make a stronger case for East Asian ancestry than either on their own.
