Ancestry DNA testing is a test in which your genetic information is used to determine the geographic origins of the person’s recent ancestors. These DNA test kits have become quite popular. According to a recent study, almost 26 million people have used these processes from direct to consumer companies worldwide. In addition, these DNA testing results provide information regarding a person’s ancestral roots. Similarly, they also help you connect with your distant relatives, like fourth or fifth cousins. This data can be quite helpful when a person doesn’t know about their ancestral roots, like adoptees and descendants of forced migration processes. These Ancestry DNA testing processes are used beyond their original purposes like they are being used in trials in order to confirm the crime of a suspect or rule him out. In a clinical setting, a person may share their test results with an expert, as these test results will help you with many healthcare decisions.
How does the Ancestry genetic testing work?
genetic ancestry testing compares a very large number of DNA variants present in the individual with the frequencies of these variants with the reference populations sampled from across the world. As a result, there would be a geographical region in which that individual variant will have a high frequency, so that location would be the most likely place of an ancestor that has transmitted the variant to the person being tested. Additionally, ancestry testing is performed for MTDNA, which a person inherits from a mother, and also for Y chromosome DNA, which is inherited from a father to a son. Additionally, a more descriptive assessment of the ancestry can be conducted by evaluating half a million or more autosomal variants that are inherited from both parents. Most of the common
SNVs are assayed with the usage of DNA microarray; however, DNA sequence data can also be used. In autosomal testing, it is generic to portray the most likely geographic origin of a group of SNVs located in the chromosome segment. In order to estimate the ancestry derived from each geographical region, the percentage of SNVs originating from that specific region is calculated.
Helping you in decision-making:
Ancestry DNA testing can be very crucial as the ancestry information frequencies of genetic risk variants differ with the ancestry. However, these risk variants are not assayed directly by ancestry tests. In addition, some of the DTC ancestry testing companies provide health reports in which they thoroughly test a limited number f DNA variants that might be linked with conditions like Alzheimer’s and breast cancer disease or less common DNA conditions like polycystic kidney, cystic fibrosis, and many other inborn errors of metabolism.
In many genetic research studies of health & disease, ancestry information has replaced the utilization of racial categories. As there is an enhanced accuracy compared with self-reported ancestry, genetically estimated ancestry can enhance the statistical power to detect genetic risk factors for common diseases in genes. Sometimes these risk factors differ by ancestry, and the risk factor is evaluated with multiple DNA variants.
People changing their identity:
A study shows that it is the white people who adopt new racial or ethnic identities as their initial identities are very bland, and they do not provide enough sense of belonging. Sociologists have called this factor color capital, which means connecting with something that is more interesting and exotic than being just white. On the other hand, the other groups felt a strong sense of cultural & political connection to their existing racial & ethnic groups. They found the results very interesting and didn’t change their identities. In addition, the black & Latino test takers knew they had mixed racial ancestry due to the racial mixing within their group.
Consequences of the testing:
ancestry DNA testing might seem like harmless fun, but there is a downside. When whit adopted an exotic new racial identity, this factor creates a view that race is a costless thing and can be enjoyed without real consequences. As a result, there would be a false view that race has no consequences these days. Some people suggest that these tests may increase the essentialist beliefs that created a view that racial groups have unique abilities & skills that are caused by their genes and that has previously been thought of as eugenic, discrimination, and exclusion.
