How does an aunt show up on ancestry DNA?
Your aunt or uncle shares 50 percent of their DNA with your parent (their sibling), who shares 50 percent of their DNA with you. The reverse is true with a niece or nephew; you share 50 percent of your DNA with their parent, who shares 50 percent of their DNA with their child (your niece or nephew).
Percent DNA Shared by Relationship
| Relationship | Average \% DNA Shared | Range |
|---|---|---|
| 1st Cousin | 12.5\% | 7.31\% – 13.8\% |
| 1st Cousin once removed | 6.25\% | 3.3\% – 8.51\% |
| 2nd Cousin | 3.13\% | 2.85\% – 5.04\% |
| 2nd Cousin once removed | 1.5\% | 0.57\% – 2.54\% |

How many generations back is 2 percent DNA?
To find where you get your 2 percent DNA, you will have to search back to about 5 or 6 generations. This would be your great 4x great-grandparents. To figure this out, you will need to use the 50\% DNA inheritance rule.
You’re equally related to your parents and siblings – but only on average. It’s often said you’re equally genetically related to parents as (full) siblings: your ‘relatedness’ is a half. That means the chance that a bit of your own DNA is shared with your mother (by inheriting it from her) is 1/2.
