    Can Centimorgans be wrong?

    Yes, it is possible for distant DNA matches to be false. It is most common to have false DNA matches that share a single segment that is smaller than 10 centimorgans (cMs) in length. The technical term for coincidentally identical DNA segments is identical-by-state.

    What percentage of DNA tests are wrong?

    Tests that test the DNA shared between a child and a parent can have a low chance of offering a false positive or come back inconclusive. However, when it comes to the modern DNA testing process, the chance of something being wrong or misleadingly inaccurate is less than a 10% chance.

    Is Ancestry .com safe?

  • The process itself is complex and tedious, and can give results that may be hard to interpret.
  • Can AncestryDNA tell blood type?

    It won't tell you your specific blood type outright as that is not what the test is specifically looking at or for. You'd need a doctor to do a blood test.

    Centimorgans (cM) are units of genetic linkage between two given individuals. For example, if you share 1800 cM with an individual, that means you share around 25% of your DNA with them. A strong match will have around 200 cM or more.

    Can a DNA test be faked?

    Can a child have two biological fathers?
