If a relative committed a crime and is caught because of a DNA test I did, how is that my problem?It has certainly caused huge issues in some families.

Families in that situation have said it tore their family apart. That is how it would be your problem.If a relative committed a crime and is caught because of a DNA test I did, how is that my problem?

I agree to a point. People can be arrested under pretty flimsy circumstances.Still not my problem. If you rape, murder, etc someone that’s YOUR problem.
I’ve told my kids that I’d you’re arrested don’t call me because I won’t be bailing you out.
One of the difficulties for women is that you only get the maternal geneology because you don't have the dreaded Y chromosome.
So, I have to ask, none of you were concerned that submitting your DNA could expose a family member as a criminal? We have several major cases here where police linked DNA information from the testing sites to relatives of those who submitted the DNA who committed crimes and left DNA behind.

I used 23&me and was contacted by a gentleman in his 80s who was adopted in 1939. He is the biological son of my Grandmother’s younger brother. The gentleman had been searching for years for his Father who was not named in his birth certificate. He just wanted a name, which he now has. Sadly his Father died in 1945.
Can someone explain to me how geography affects DNA? I understand how DNA from China, Africa, and Europe would be different, as we're talking about different races. But how in the world does DNA differ between England and France, or Germany and Austria?
Racial differences I obviously understand. But how can DNA be identified by an arbitrary line on a map between neighboring countries? Is American DNA that much different than Canadian DNA?
It doesn’t. At least not with the scientific technology we have now. What people don’t tell you is you have to select the percentage of accuracy you want. To get results like the op had you have to opt for 50% accuracy or less. If you want a higher percentage of accuracy your results will have categories like European, Asian, etc.
From what I understand what they do is look at the markers for say eye color. If you have red hair the computer looks at what country has the most people with red hair and says you must be from that place. Problem being red hair occurs in more than one place and they are comparing to the modern genetic make up in those areas not historical genetic frequencies. That is why the make up changes every time the company updates its database. They don’t really know, you might as well throw darts at a map of the world and use that.
Why would I be concerned about a criminal being caught for a crime they committed?

Well, I guess all families are different. I can say that in the two court cases here it has DEVASTATED the families. I think it would devastate my family.Why would I be concerned about a criminal being caught for a crime they committed? It isn't my problem.
Geography does not affect DNA. Geography helps explain DNA’s origin. If you have certain genetic markers they can say “the people with this combination of genes came from here.” The red hair thing above is oversimplified. There are several different ways to arrive at red hair, genetically. There is not one single gene for hair color or eye color (sorry 7th grade science teachers). The combination of patterns is how they assess your genetic background. They were accurate down to the county level of where my great-grandmother was from in Ireland, and that’s not information that I put into my family tree anywhere (so they’re not just aggregating my own data which has been a statement I’ve seen made in the past in other places). And “race” isn’t really much more genetically significant than hair or eye color honestly. It’s more of a social difference than a genetic one. People love to be able to categorize each other into “same” and “other.”Can someone explain to me how geography affects DNA?

If my family member committed a crime, I would be more concerned with how devastated the victim’s family would be not knowing the perpetrator.Well, I guess all families are different. I can say that in the two court cases here it has DEVASTATED the families. I think it would devastate my family.
Not on 23andMe you don't. They even provide maps showing the area of a country your ancestors were most likely from, which were very accurate based on what I know (county Kerry in Ireland, southern Poland, southern Germany).
Basically, when you've had a population living in the same area for a long period of time things get more and more inbred, so to speak, and less genetically diverse. So when they start looking at genetics they can pinpoint that these genes are most common in one area, those genes are most common in another area.
We each get half our DNA from our father and half from our mother -- but the DNA we get is random. In other words, you got different DNA from the same parents than your brother did. That's why siblings, even twins, look different.I believe that is caused by the databases the company is comparing against. As the databases grow, the results theoretically get more accurate, and will change over time.
