Haha yeah walrus the way somebody talks really shows what their DNA is
He is a white Italian the dna heritage tests canât tell shit unless they had samples from 200,000 yeas of your relatives he is white, called for the bombing of nothkorea and is white
DNA kits â how do they do the testing
The first thing we need to make clear right up front is that none of the DNA kits by mail test 100% of your DNA. They actually look at a tiny portion, much less than 0.1%, of your DNA, then compare that to a database of DNA that each company creates from all of these tests.
They donât compare whole genes, which contain up to 27,000 nucleotide base pairs. Actually, these DNA testing companies look at SNPs, which is one single base pair in the gene. Though the SNP may indicate a key difference between genes, itâs sampling one tiny portion of a gene.
Currently, a company such as 23andMe has identified 600,000 SNPs, or about 6% of the 10 million SNPs in the human genome. In other words, these companies are making conclusions without a full analysis of the other 9.4 million SNPs which obviously have much more data that could be critical in disease diagnosis and ethnicity.
This is the first step where error is introduced into the equation. If these DNA kits say you are 38% German, whatâs the error around that number. Does it vary from 0% to 76%?
Just to be clear, paternity tests are extremely accurate. They compare a handful of DNA loci between two individuals. The more that the loci are exactly alike, the higher degree of relationship between the two individuals.
But letâs assume that the results are accurate. What can these home DNA kits really tell you about your ethnicity?
Are you related to William Shakespeare?
The answer is that a DNA test isnât ever going to answer this question. If you can prove youâre a direct descendant of Shakespeare, itâs not going to be through home DNA testing.
Letâs look at this way. Shakespeareâs children are, based on random genetic inheritance, only 50% related to Shakespeare (the other 50% related to the mother). Shakespeareâs grandchildren will only be 25% related to him.
If you consider that thereâs been 16 generations since Shakespeare (assuming 25 years to a generation), any direct descendants of him would share 0.00153% of his unique genes (see Note 1). In other words, DNA testing could not possibly tell you if William Shakespeare is your great great great etc. grandfather.
The only way to make that claim is through actual historical records and genealogy. Youâd have to establish that relationship between you and him apart from DNA testing.
Are you 38% German?
This is where things are problematic. Do you think that in some way we have markers for Germans that allow us to tell that youâre not French? No, there really isnât.
Generally these genetic test are better at telling the geographic location of your ancestorâs DNA rather than their ethnicity. Europe today is clearly divided into countries. You know youâre in Germany or France because German or French is the language. There is a non-continuous variation between what constitutes a German or French based on an artificial border between those countries.
But in fact there is a continuous variation genetically between a French village to a German village on the other side of the border. There isnât a sudden genetic change at the border, but a blend from one location to the next.
Thereâs a small French city in the eastern part of the country, Mulhouse, which has switched between Germany and France several times over the past centuries. It is now a solidly French city.
Do you think that Mulhouse residents are 100% French or German? No, they are some admixture from the centuries of invasions and conquests.
Now, these home DNA kits may identify you as âFrenchâ because it indicates youâre from a region of France. But donât start speaking French, because you could be ethnically German.
And, thatâs just one example.ha ha ha ha ha
Idiot, German and French are the same damn thing. I am Armenian with 42% Arabic y chromosomal DNA
