Since the DNA that gets passed down to their offspring is randomly selected, this explains the range of about 19-33\% of shared DNA between aunts/uncles and nieces/nephews.
How much DNA do half first cousins share?
Half 1st cousins share 6.25\% of DNA, while full 1st cousins share 12.5\% of DNA. In a perfect world where averages were the rule, these relationships would be easy to distinguish by DNA. But DNA doesn’t follow the average, so a Half 1st cousin could share as much or, in some cases, more DNA than a full 1st cousin.
Can you get genes from your aunt?
You share about 25\% of your DNA with any aunt or uncle, shown in yellow. Your 25\% shared DNA came from your grandparents. But here’s the really important part: ALL of the DNA that your aunt or uncle carries is your ancestors’ DNA too – even though you only match your aunt/uncle on 25\% of their DNA.
Can an aunt do DNA test for nephew?
Avuncular DNA testing is a DNA comparison performed between an aunt or uncle and a niece or nephew. An avuncular test is best with the alleged parent’s full sibling, (brother or sister), sharing the same mother and father.
How much DNA does a niece share?
Percent DNA Shared by Relationship
| Relationship | Average \% DNA Shared | Range |
|---|---|---|
| Parent / Child Full Sibling | 50\% | Varies by specific relationship |
| Grandparent / Grandchild Aunt / Uncle Niece / Nephew Half Sibling | 25\% | Varies by specific relationship |
| 1st Cousin | 12.5\% | 7.31\% – 13.8\% |
| 1st Cousin once removed | 6.25\% | 3.3\% – 8.51\% |
How much DNA would a niece share?
Aunts, uncles, nieces, and nephews 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). Testing an aunt or uncle can help you determine which side of the family some of your DNA matches are on.

How much DNA do I share with my niece?
You share about 25 percent of your DNA with a biological aunt, uncle, niece, or nephew. Your aunt or uncle shares 50 percent of their DNA with your parent (their sibling), who shares 50 percent of their DNA with you.
Do aunts and nieces share DNA?
Also question is, do aunts and nieces share DNA? Uncle/aunt-niece/nephew pairs share between 78.48\% and 79.57\% of SNPs (25\% of DNA in common) Grandparent-grandchild pairs share between 77.96\% and 80.59\% of SNPs (25\% of DNA in common) Subsequently, question is, can you inherit genes from your aunt?

What percentage of DNA do you inherit from your grandparents?
An individual can’t “get” or “receive” or “inherit” genes or DNA from anyone but their parents. Whatever percentage of DNA that they have in common with other family members (25\% between a niece and uncle) is the percentage that was passed down from their most recent common ancestors: the grandparents.
Is it correct to say that the niece inherited it from Uncle?
It’s just not correct to say this was inherited by the niece from the uncle. Instead, you would say it is DNA inherited from the grandparents by both the uncle and the niece (through the parent of the niece). What does Google know about me?
