Can I find out my race/ethnicity?

Yes. Autosomal tests are best for this because they look at your entire gene, at all lines. Check out the DNA Fingerprint Test. The maternal and paternal lines can be measured with more precision by today's state of genetics, but remember they are but two lines among many. Each generation you go back, the number of your ancestors doubles, so that for 1500 CE (the beginning of European immigration to the Americas), a person alive today has, in theory, over 34 million lines. In practice, populations go through bottlenecks and people do not marry randomly, so the number is a lot lower. Multiplexing DNA tests cannot measure "crossover" patterns from the male to female line, only the "outside" male-male and female-female lines. In some cases, your outside lines may not be the dominant ones in your genetic makeup. For instance, a British schoolteacher was found to have a sub-Saharan male ancestor, believed to have come over as an African slave with the Romans. About 30 percent of American blacks have a Y chromosome that originated in Europe and is Caucasian. To get an ethnic summary of Caucasian, East Asian, African, and Native American DNA, you may order our WHOLE DNA or EurasianDNA 1.0 test. To get even more detail down to the country level in Europe or region of the Americas or Africa for Native American and African DNA, order the DNA Fingerprint Test. All these work by sampling markers taken at random from your entire genome. Read our Statement on Ethnicity.
