How Are Aunt-Uncle Test Results Determined?

Results are reached based on two factors: the number of genetic matches between the child and the presumed aunt or uncle and the statistical likelihood that those matches would occur randomly. These two numbers are calculated and compared to reach a percentage of probability. The higher the percentage of probability, the likelier it is that there is an aunt/uncle relationship. Bear in mind, however, that an avuncular test doesn’t have to show 100 percent probability to be deemed scientifically accurate; if the percentage shown on the report is 90.0% or higher, it is generally accepted that the results are conclusive.
