How accurate are the minor (<10%) admixture scores?
• Pedigree studies have shown that the level of admixture follow known inheritance patterns, supporting the validity of these low values. However, as stated above, the confidence intervals are important for understanding your results and the scores are the most likely estimates from your DNA. If you confidence interval overlaps zero your value may be within the statistical noise threshold of the test and should be considered a possible result. As the number of markers tested goes up the statistical noise should decrease as evidence in the change in confidence interval size between the 2.0 and 2.5 tests.
