What Does X Match Mean in Family Tree
Do you lot want to know what it means to have an 10-DNA match on Family Tree Deoxyribonucleic acid? In this post, learn the answer, too equally how to figure out how your X-Deoxyribonucleic acid friction match is related to you.
X-Deoxyribonucleic acid matches can provide clues into aspects of your family tree that you might non have known otherwise. In addition, the unique inheritance design of X-DNA can give you details about how you may be related.
Family Tree Dna is a great DNA testing service and the website allows united states of america to view in-depth details about our genetic connection to our matches. It might seem complicated at first, just this mail service will requite yous the data that you need to brand sense of your X-Deoxyribonucleic acid matches.
What does information technology mean to take an X Dna Friction match on FTDNA?
If you accept an X-DNA match on Family Tree Dna (FTDNA), it ways that y'all and your match share at least one identical Deoxyribonucleic acid segment on your X chromosome.
Your 10 chromosme is one of your sexual activity chromosomes. If y'all are female, you have two 10 chromosomes, and if yous are male person you lot have an X and a Y chromosome.
In other words, if you have an 10-Dna lucifer on FTDNA, you and your match share identical genetic material on your sex chromsome.
For males, the meaning of a lucifer on the X chromosome is more than straightforward. Males don't inherit X-Deoxyribonucleic acid from their father, which means that the X-DNA shared with a match must have come from their mother's side.
Females inherit X Deoxyribonucleic acid from both their mother and father. The X-Deoxyribonucleic acid that they inherit from their begetter came from their paternal grandmother, as the grandfather did not pass down Ten-DNA to his granddaughter.
10-Deoxyribonucleic acid inherited by females from their mother came from a complete X chromosome passed down from their father, and a recombined X chromosome passed downward from their female parent.
How are yous related to your X-Dna match on Family unit Tree DNA?
In lodge to figure out how y'all are related to your 10-Dna matches, more study of the way X-DNA is passed down is necessary.
Males and 10-DNA matches on Family Tree DNA
We already know that males can eliminate their entire paternal side when searching for possible connections. In other words, an X-DNA match cannot have come from their father's side.
A male person can look to his mother's lines to find how he might be related to his X-DNA friction match. Understanding the inheritance pattern can aid us further eliminate potential ways that males are related to their X-DNA matches.
Since a male person's female parent inherited X-Deoxyribonucleic acid from both of her parents, nosotros tin can't eliminate them. Just, we do know that a male'southward paternal gramps did not pass Deoxyribonucleic acid down to his grandson.
For me, it helps to draw a simple family chart on newspaper. This style, I know which lines of the tree an X-Deoxyribonucleic acid match could perchance be related on.
Depending on how large the shared X-Dna segment is, I might not need to go very far dorsum on my nautical chart. One time I accept narrowed down a few lines, I tin compare those surnames to the male's X-Dna match'south family tree.
If yous haven't yet started building a family tree, definitely check out my book which is a guide to family unit tree building nuts.
Females and X-DNA matches on FTDNA
Since females become X-DNA passed down from both of their parents, nosotros don't get to easily eliminate 50% of our ancestors as possible connections like nosotros do with males.
The aforementioned basic inheritance pattern holds true for females, however. When I'k trying to visualize X-Dna in my caput, I become a little dislocated.
Alibi my "chicken scratch" handwriting below, if you will. This is the type of drawing I will ofttimes make (again and again) when researching my X-Deoxyribonucleic acid matches.
The female Dna tester inherited X-DNA from both of her parents, as indictated past the (X) next to the ancestor'southward name. We can meet that NO X-DNA got passed down from her grandfather.
If it's a close Ten-DNA friction match, nosotros might already know which surnames to compare. It'south specially helpful if you lot have access to your DNA match'south family tree data, if possible.
We can go further dorsum in our chart, too, to eliminate more than possibilities in search of a mutual antecedent.
If we draw out the nautical chart calculation another generation, we will encounter that a female could accept inherited X-DNA from:
- Her father's maternal grandfather
- Her father's maternal grandmother
- Her maternal grandparents
- Her mother'due south paternal grandmother
- Her mother'due south maternal grandparents
If you want to, you can print out a pedigree nautical chart from your tree and trace the inheritance of X-DNA back, eliminating potential lines and surnames.
And so, compare your tree to your X-DNA friction match'south tree in order to find common surnames. The common surnames could indicate how y'all are related to your X-Dna match.
You tin be related to your Ten-DNA friction match in more than one way
Y'all can be related to your Ten-Dna lucifer in multiple means. If you lot share autosomal DNA with your DNA friction match, you could take inherited information technology from the aforementioned mutual ancestor that passed down the X-Deoxyribonucleic acid to you.
Alternatively, yous could be related to the Dna match in two or more ways, meaning the X-DNA was passed down from a unlike common ancestor than the ane who passed down the autosomal DNA.
This issue likewise occurs with autosomal DNA matches.
Conclusion
I hope that this post has helped y'all understand more than nearly how to understand your Ten-Deoxyribonucleic acid matches on Family unit Tree DNA and how to figure out how they might exist related,.
If you have any questions near something that you read in this post, or if you lot have any additional questions about your 10 Deoxyribonucleic acid matches on FTDNA, please join u.s.a. in the discussion below.
