While advancements in medicine are advancing rapidly genetic ancestry testing The purpose may be to provide information about ancestral roots and to connect with distant relatives. Special adopted or immigrants Are there any deviations to be observed with this method?

Between companies that carry out the tests or between identical twins outcome differences is this possible?

Various ancestry profiles can be reported with a DNA sample.

You may think that when identical twins are given DNA samples, the results will be the same. However, that is not the case. One company’s results were different. one of the twins 13 percent European While in the other this result was only 3 percent.

Reasons for assigning different profiles include significant differences in the previous inhabitants of an area. Migrate It is also available. The fact that the term ancestry is subject to various interpretations, such as geographical, historical, cultural and religious, introduces errors or ambiguities in genetic root derivation.

Well, even if we assume that the tests were performed with the correct methods, the results are Why could things turn out differently?

Every company’s DNA databases are different.

DNA testing companies, uses its own databases when evaluating the results. The larger and more diverse these databases are, the more accurate the test results can be. Some like Africa and South Asia ethnic groups Results for individuals belonging to these groups are less accurate because they are less represented than others.

Moreover genetic sciences Considering that there are new discoveries in the field, companies genetic knowledge base It must be updated regularly. Only in this way is it possible to approach the results more accurately.

Genetic testing does not sequence entire genomes.

Companies, possibly Not all genetic variation is taken into account. Millions of single nucleotide polymorphisms found in DNA (SNP) focuses on. Although this method is used because SNPs are passed from generation to generation, this is where the database comes into play. SNP results must match a database of people with known ancestors.

Another problem at this point is that there is a tendency to make big mistakes, even if they are small. Even though 99.9 percent accuracy is reported in the genome sequences, 1,000 errors processing 1 million places claim.

We must not forget that it is a computer program that makes the predictions.

As a result of the DNA test, 20 percent are European, 30 percent Chinese, etc. You may come across data. Because algorithms are based on the person’s SNP data different combinations of ancestors doing. This essentially means a lack of distinction between ancestors that are genetically very similar.

While results may vary from person to person, the effects may also vary.

While some users may have a different ethnicity than the ethnicities they know, others may receive results that confirm their family stories and histories. Unexpected findings on ancestral origins and family relationships psychosocial consequences can also give birth.

Moreover, while the chance of locating a first-degree cousin with such services can be 100 percent, the rate of locating a third- or fourth-generation cousin can drop to 15 percent. Therefore How accurate is it to create a complete family tree? Could it be?

It is better not to take action right away.

As a result of a DNA test If 10 percent of you are Norwegian and you do not have a lineage document, you should not immediately start looking for your ancestors. This percentage will probably change with a subsequent test.

If you get the same consistent results from different companies, you can buy your plane ticket and move to Norway. But keep in mind that the most reliable indicator of your ancestry is not an ethnicity estimate. Names of people you matched with and family trees.
