The very simple answer is that if we have an XDNA match with another person then that person has to be on our mother’s side of the family.
Is X DNA maternal or paternal?
The X is a recombination of the two X chromosomes the mother inherited from her parents. When a male tester has a match on X-DNA the entire paternal half of his family tree and portions of the maternal half can be excluded as a source of the X-DNA match.
What does X match mean in DNA results?
When an XY male finds someone who is a match for their X-DNA, it means they have a shared ancestor with that person on their mother’s side. However, it’s rare for an X-DNA test to be done on its own. That’s because this test only looks at one chromosome and therefore yields more limited results about your ancestry.
What does an X Match mean on Family Tree DNA?
If you have an X-DNA match on Family Tree DNA (FTDNA), it means that you and your match share at least one identical DNA segment on your X chromosome.
What does it mean if you share x DNA?
Maternal uncles and nephews would be expected to share segments on their X chromosomes whether their parents were related or not. On the other hand, if we are talking about a paternal uncle’s X chromosome, then sharing big chunks of the X chromosome could mean that the parents may have been at least distantly related.
Can a woman trace her paternal DNA?
Yes, a woman can trace her father’s DNA through various means. Through autosomal DNA tests or Y-DNA tests taken by herself, her father, brother, or paternal male cousins descended from their common grandfather through an uncle, and test results from other relatives, females can trace their father’s DNA.
Can you be related to someone and not share DNA?
Yes, it is possible to share a small amount of DNA with someone and not be related. In other words, it’s possible to share genetic material and not share a common ancestor or any identifiable genealogical connection.
