For example, if a match is my second cousin and also a second cousin to another match, chances are really good that we all share great-grandparents. Remember that 23andMe has taken a stab at genetic tree construction on their genetically created (now nearly unreadable) Family Tree, found ...
This could indicate that you have a DNA match who might not have enough shared DNA to match everyone in a particular cluster, something that you would see in a more distant relative like a 2nd cousin of yours not matching a lot of your common 3rd cousins. That is basically how clusters...
Kitty has five segments in common with her double third cousin and Shipley has seven. See my DNA basics page for more information about what this all means. So many of my family members have tested their DNA that I have created a special category for them all called Our Family Results. ...
However you need to be sharing to compare people you match to each other. For example, one distant cousin overlaps with Dick on the master chart but when I compare him and Dick to each other there is no match there. Thus I know that person’s segment is from the other side, maternal...
If your grandparents are not related to each other, the Leeds Method works well. It also helps if they came from very different areas so there’s little chance that they might have a surprise connection or that a match might be related to two of your grandparents. ...

FGG, FGGS; also investigative genetic genealogy)— the use of genetic genealogy techniques to identify human samples, either from a crime scene or unidentified remains; FamilyTreeDNA and GEDmatch both sell access to their databases...
All BLAIRs are encouraged to participate in the Blair DNA Project. Male BLAIRs may participate directly. Because females do not have the Y-chromosome they can only participate through a male BLAIR relative (father, grandfather, brother, uncle, cousin). Each male participant will provide a mout...
A false positive match caused by haplotype switching between maternal and paternal chromosomes. Consider the example to the left. Person A and Person B each have two copies of the chromosome, one paternal (blue) and one maternal (red). Neither sequence (haplotype) from Person A matches either...
I had adebate today with my cousin.She thinks that you can use DNA to automatically solve a crime without any suspects. I tried to explain to her and her mom that you need a link (a suspect) to get dna from first to possible solve a crime. Also that you can’t just look at some...
