Does DNA show racial DNA and if so, does DNA show where or from whom that racial DNA came/comes from?

How far back can DNA be traced?

Did not know what forum to put this in. Evolution?/Creation?

DNA to show where a person comes from, is absolute rubbish! I see people on YouTube say that they sent tests to some lab, who told them that they had part London, Manchester, Liverpool, etc, in their DNA! HOGWASH. If a person is white Anglo-Saxon, for example, it will be almost impossible to say if they are English, or even from some other European countries, like Germany, who share much of the English DNA, as the same Germanic Tribes, that settled in Germany, also came to England.

My understanding is "yes" there are DNA markers which reveal if a person has ancestry similar to Asians or Africans, or Native peoples, or Caucasians. My DNA testing revealed I do not have a drop of Native Peoples blood in me. But loads of Western European blood, probably from Ireland, England, and the Netherlands.

Autosomal DNA, which determines your ethnicity, goes back about six to eight generations or around 150-200 years, for most people. On my father's side of the family, where men tend to live to an old age and have historically sired children well into their 70s with much younger wives (they survived the death in childbirth of three, four, and even five wives!), six to eight generations is 250- 325 years.

For ancient origins, you’ll want a YDNA or mtDNA test. However, women do not have YDNA, so they would need a male relative to get tested instead. An mtDNA or mitochondrial DNA test will show generations that are both recent and distant. The YDNA tests will show generations that are both recent and distant. However, there are a few different types of tests for YDNA, including single nucleotide polymorphism (SNP) and the short tandem repeat (STR).

SNP tests
The YDNA SNP test will help you confirm your haplogroup so you can discover your ancient ancestral origins. They will trace the earliest anthropological resettlements as well as the most recent prehistoric relocations.

STR tests
On the other hand, the STR test will trace the male lineage back to both ancient and genealogical times. You can check the matches on your account to discover your genealogical connections. This will also tell you the possible regions of the world where your linage originated from.

Thanks. Not sure I understood all I read but thanks.

I watched a couple of episodes on TV where an analyst used the data base held by DNA testing firms to find suspects that had left DNA at crime-scenes. Didn't scare me, as I am about the worst my family has to offer.

I am not a fan of the DNA ancestry industry.

I think the questionable data they provide of "ancestral links" is of very little value compared to what individuals are giving up by handing over their DNA to these corporations who may further use that information in ways that could harm you intentionally or unintentionally.

1. The data is questionable in that what they are actually doing is looking at how common certain genes are in certain places today and extrapolating that if you have those genes you likely had ancestry from those regions. But we don't know when people with those genes arrived in those places. What does that give you except for a few minutes interesting what if scenarios running in your head.

2. Intentional harms might be further selling that data to those who want to develop a more detailed profile of you say like your medical insurance company wanting to assess your risk for chronic disease and adjust your premiums to that risk

3. Unintentional harms might be having that data hacked and used to frame you in a crime scene.

I think the risk far outweighs the benefit of these services.


This is different from having a genetic counsellor who can perform a completely private study of your DNA looking for markers of genetically inheritable disease that you could pass on to your children. This can be very valuable if used correctly and they often have stricter privacy policies than the DNA ancestry companies. But is still not without potential harms of unecessary anxiety about conditions that are very unlikely. It also opens up the door to the ethical dilemma of genetic modification not just for disease but for non-disease traits and "designer" babies.

Don’t ask me how (privileged information), but I’ve been able to trace mine back through Noah all the way to Adam and Eve.
