More distant relatives share dramatically less DNA with us. This table provides estimates of shared DNA percentages for various relationship typesĪs you can see from the table above, we share a considerable amount of DNA with our parents (about 50%). It is possible to share slightly more or less DNA than than what you see in the table below: Parent/Child We have enough data to determine the expected percentage (%) shared DNA for a number of common relationships. Expected percentage (%) shared DNA for common relationshipsįortunately, we know a lot about how much DNA people of most relationships share with each other. It is possible for third cousins to share very little DNA, or no DNA at all, meaning that a fourth cousin might share slightly more. There is a range of shared DNA that we expect to see between relatives. This is almost always true, unless the percentage of DNA shared suggests a much closer relationship than previously known.įor example, you might have a fourth cousin who shares a slightly higher percentage of DNA with you than a third cousin. Percentages shared with distant cousins are not as significant when trying to figure out how you might be related. This is especially true when referring to close relatives. Generally speaking, the higher percentage of DNA that you share with your DNA match, the closer the relationship. Of course, the closer the relative, the more significance to us the shared DNA will have. Thus, we can view anyone who shares at least 1% of their DNA with us as a potentially close relative. 3-2% of their DNA with us, as close relatives. This is because we define third cousins, who share. What percentage of shared DNA is significant for Ancestry DNA matches?įor the purposes of genealogy and family relationships, a significant percentage of shared DNA is 1% or higher. They share 785 cMs of DNA with each other, which happens to be about 11% of their total DNA. The DNA match above is the great-granddaughter of the test taker. The red circle indicates the percentage of DNA shared between the DNA match and the test taker The number will appear under your estimated relationship, as show in the image below. You can see the percentage of DNA shared with your match directly on your DNA match list.
