The rise of direct-to-consumer DNA testing has made this testing process a new frontier. Today, people can get their DNA tested and after several weeks receive all sorts of information back in the mail or just by logging into the website.
One of the most common uses of DNA testing is in uncovering family genealogy. Using consumer DNA testing services, individuals can now uncover their family lines going back several generations. One can identify his or her racial makeup, familial ties, and geographical background.
There are many online services offering DNA testing for ancestry purposes, including leaders AncestryDNA, Family TreeDNA, and 23andme. For a quick overview & comparison of each test, check out MyFamilyDNATest.com.
From the time when the double helix structure was drafted in 1953, Deoxyribonucleic acid (DNA) technology advanced at an exciting speed. From agriculture to microbiology, DNA splicing and mapping procedures have turned both science and community upside down.
Deoxyribonucleic acid (DNA) is what determines the individual physical nature of each human. Genetics can decide one’s eye color, hair color as well as the height, still, there is so much more which DNA reports. These include solving crimes to ascertaining family relationships to the latest medical progression, the specific information available from DNA testing is improving lives.
Nowadays, it takes just two days to run a DNA test, either for tests exploring a single genetic marker or whole-genome sequences. However, most labs may take longer (up to 6 weeks) depending on some factors such as the kind of the request and their individual procedures. Costs have decreased as well. It was reported in 2012, whole-genome sequencing expense was over $13,000; in 2014, it seems a $1,000 test is expected. Now in 2018 a starting DNA test kit costs below $100.
The DNA technology has increased the effectiveness of defendant credentials in crimes as well as the degrees of arrests and prosecutions. Exceptional paternity tests are now perfect without maternal specimens and people are now capable to trace their hereditary ancestry and determine what makes them who they are. Again, some of the very interesting developments exist in the medical area where personalized medication may soon be a common phenomenon.
The Deoxyribonucleic acid testing is very specific now that physicians are able to record the prescripts depending on a person’s genetic composition. DNA guidance form and manage enzymes that metabolize drugs, influencing both the degree of responses to ingredients metabolism. Having knowledge about one’s genetic enzyme profile enables doctors to provide more precise dosing, chose the most efficient drugs and also assist avoid adverse side effects.
Diagnosing illness as well has been made easy by the DNA testing technology. For instance, Genome sequencing aids in identifying mutations in cancer cells and cell’s reaction to treatment. Identifying pathogens in the field of medicine is also possible by quickly comparing a DNA specimen to online databases. Although this is not yet become a common practice, such software lately assisted save a kid’s life when it discovered a harmful bacterium that leads to brain inflammation. The 48-hour events let his victorious medication.
In intensive care units, genome sequencing is supporting to save the lives of newborns. By administering a whole-genome sequence, physicians can identify genetic ailments and possibly look for a medication that is distinct to an individual baby. Such examination can also recognize markers that might harm other members of the family.
Analysis has revealed that single-gene modifications lead to more than 3,500 illnesses, though approximately 3,000 of those do not yet have medications. More examination will lead to more discovery, which can then lead to better, even personalized medications. With developing levels of detail, high-speed analyses, and lowered costs, DNA examination is making futuristic hopes into the present.
There are quite a number of online services giving Deoxyribonucleic acid examination for Ancestry purpose.
Once you receive your DNA test results, analyzing the raw data can be difficult unless you are a bit of a genetic expert. To help people make sense of the data from their genealogical DNA tests, several tools have been developed.
Below, we take a quick look at 4 of the most popular tools to use for gleaning more information from your personal DNA data.
DNAGED.com is one of the easiest platforms to use for obtaining personalized, rich reports on your DNA test results.
The site allows you to download DNA data and files from 23andme and Family Tree DNA (FTDNA).
The goal of the platform is to help create meaningful links between raw DNA test data and your family trees. In short, you get more in-depth information from your DNA test regarding your family history and background.
Another popular DNA analysis platform, GEDMatch, allows you to upload raw data from three DNA testing services; AncestryDNA, FTDNA, and 23andme. This platform is free!
Using GEDMatch.com, you can:
- Check for DNA matches with other people who have used different DNA testing services.
- Perform triangulation. This is a process of comparing your DNA with that of known family members to determine how you are related.
- Determine exactly how much DNA you share with your matches.
- Learn about your ancestry composition (image). You can check whether you have Native American or European ancestry.
- Check whether two people are related, for example, your parents.
- Determine family connections as far back as possible by carrying out X-chromosome comparisons.
For instructions on how to upload your data to GEDMatch.com watch this excellent tutorial.
On PROMETHEASE.com, you can upload your raw DNA data directly from your computer or import it from 23andme. The platform also accepts uploaded data in many formats from most DNA testing services including FTDNA and AncestryDNA.
The analysis takes around 15 minutes, after which you will receive a personalized report that summarizes the important details of the data and directs you to the scientific literature to learn more.
The report provides genealogical details to help you learn more about your ancestry and health information regarding your genetic risks for certain illnesses such as Alzheimer’s.
One analysis costs $5.
It is important to note that Promethease.com uses information from SNPedia to analyze DNA data and create reports. SNPedia is a wiki on human genetics.
Interpretome is a free DNA analysis tool created by genetic experts from Stanford University. Unlike most other analysis platforms, it only supports data files from Lumigenix and 23andme. This tool has been renamed to GENOtation.
Though the report will contain genealogy information, it is a bit scarce when it comes to details concerning genetic health risks.
One of the more exciting tools you will find useful is the Principal Component Analysis (PCA) package. Using this tool, you can get your genome analyzed to determine your global ancestry. The result is displayed in the form of a position on a global map.
Using another tool, you can also check how much of your genome is inherited from the Neanderthal man.
Something important to note is that all computations are performed on your computer browser and no personal data is sent to any server.
Compatible browsers include the latest versions of Google Chrome, Mozilla Firefox, and Safari.
Human genetics is a field that continues to grow every day. There are still a lot of things experts have yet to figure out.
As a result, it is recommended that you take your DNA tests report with caution, especially when it comes to health information. None of these tools listed are intended as an endorsement from this website.
But for those looking to recreate their family lines, the above tools will prove to be very useful. They will be invaluable in filling in missing blanks and stretching your ancestry knowledge further back than you ever expected.
