Deoxyribonucleic acid, better known as DNA, is found in almost every cell in the human body. It contains the genetic code or instructions that determine a person's physical characteristics like eye colour, hair colour, height etc. as well as their susceptibility to certain diseases. DNA testing or genetic testing allows a person to learn more about their ancestry and health by analysing specific locations of their DNA called markers.
How DNA Test Kits Works
DNA testing companies extract DNA from saliva or cheek swab samples provided by customers. The DNA is then isolated and certain sections called markers are analysed. These markers are compared to large DNA databases that contain genetic information from various populations around the world. This comparison helps determine similarities and matches that can provide clues about a person's ancestral origins. Some DNA tests also analyse markers linked to certain health conditions to provide information on risks. The results are compiled into detailed ancestry reports and health risk reports for customers.
Ancestry DNA Testing
AncestryDNA is one of the most popular DNA testing kits for tracing family history and discovering ancestral origins. The test uses autosomal DNA markers which can track a person's ancestry back multiple generations on both their mother and father's side. AncestryDNA compares the customer's DNA against a database of over 15 million people worldwide to find genetic cousins and determine percentage estimates of ancestry from various populations. This helps paint a picture of how recent ancestrymigration and intermingling has shaped a person's genetic origins. The detailed ethnicity estimates help uncover unexpected ancestral roots.
Health and Trait DNA Test Kits
Some DNA testing companies like 23andMe and Ancestry also provide health reports in addition to ancestry composition. They analyse markers linked to inherited conditions and perform genomic analysis to determine carrier status and risk levels for certain diseases. Common examples are Alzheimer's disease, celiac disease, late-onset Parkinson's disease, breast cancer etc. 23andMe also analyses markers that can provide information on physically detectable traits like earwax type or ability to taste certain bitter compounds. Knowing these genetic predispositions helps people take preventive measures.
Privacy and Ethics Concerns
While DNA test kits provides fascinating insights into ancestry and health, it also raises privacy concerns due to the sensitive genetic information it contains. Customers need to be aware of how their DNA data will be stored, protected and potentially used by the testing company and its partners. There are also ethical concerns around genetic discrimination in life insurance and employment if results show increased risks. Reputable companies like AncestryDNA and 23andMe have detailed policies on privacy, security and ethical use of customer data. However, regulations are still evolving as DNA testing becomes mainstream.
Uses and Benefits of DNA Test Kits
DNA testing provides interesting glimpses into human migration patterns, family histories and even long lost relatives. It sheds light on the genetic diversity within populations and across countries. On the health aspect, DNA results can help people optimize preventive care according to personal risk profiles. Adoptees can potentially locate biological family members through DNA matching databases. Overall, continued advancement in DNA analysis is increasing both the uses and benefits of genetic ancestry and health testing for individuals as well as scientific research. Just knowing the instruction book of life is fascinating to many.
