Then it provides an overview of the enterprise of DNA ancestry testing: who the test-takers are, what their aspirations are, and how they interpret the results that they receive. Once this is done, some issues with tests are considered and explained, namely, the fact that different companies...
DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and anitrogenbase. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytos...
With the HVR1 (mtDNA) and HVR2 (mtDNAPlus) tests, you receive at least your base haplogroup. The full sequence is required to determine your full haplogroup. To put this in perspective, think of your mitochondrial DNA as a clock face. There are a total of 16,569 locations in your ...
The results show that one sister is 10% French, the other 0%. Both sisters share the same two parents, and therefore the same set of ancestors. So how can one be 10% more French than the other? Tests like these rely on our DNA to answer questions a...

Genotyping is the experimental procedure that identifies the differences in DNA sequence among individuals or populations. It is used to understand the connection between genotype (the underlying genetic code) and phenotype (the observable organismal structure). An individual genome is identified as a di...
