Popis: This chapter covers the different types of direct to consumer DNA tests for genealogy. They are technically similar but a bit different from those used for medical and health conditions, as genealogy tests focus on identifying “matches,” or relatives who’ve also tested based on shared SNPs or other similarities. Consumers can choose from autosomal DNA, Y-chromosome, and mtDNA tests, depending on their interests and research goals. Unlike the other tests, genealogy DNA tests compare your results with those of others and predict a relationship based on the amount of DNA you share. This adds an extra layer of complexity but is no less rewarding, and the findings can be no less surprising. Understanding how these tests work and what they show enables consumers to choose the specific ones that will be most helpful in compiling their genetic genealogy.
