Ancestry Dna Is It Accurate

Ancestry Dna Is It Accurate – This is a great question! Ancestry tests are now becoming very popular thanks to companies like 23andme, MyHeritage, and AncestriDNA (to name a few). So it’s good to ask the important question, how can they find out where your ancestors are from just by checking your saliva!?

Well, let’s start there. Usually with these origin tests you will be asked to spit into a tube and send it to the company. They then extract your DNA from the cells in your saliva. And all the important information is there, including the origin.

DNA is unique to each person. It’s like a blueprint, a map of who you are biologically. Your DNA blueprint is a sequence of four different letters: A, C, G, and T. And if you add up all the letters, it’s a code of 3 billion letters!

As you may know, you inherit a unique combination of half your mother’s DNA and half your father’s DNA. Because we all inherit DNA from our parents, we are actually inheriting copies of DNA passed down from ancestors many generations ago.

You don’t need to know all 3 billion letters to do an origin test; it is enough to know the code for several hundreds of thousands of specific places. These are individual points in the DNA that scientists have discovered can vary from person to person.

Some of these differences mean that you will have blonde hair instead of brown or blue eyes instead of green. But elsewhere it doesn’t seem to matter what version you have. That’s the difference.

These differences can be very helpful in determining the origin. Maybe at some point most Europeans have a “T” while Asians tend to have a “C”. By looking at thousands of such differences, we can begin to predict where your ancestors came from.

Nowadays it seems very common for people from different countries to meet and have children. However, traveling 10,000 years ago was not as easy as it is today!

This means that people in a certain area tended to share DNA. Because travel was difficult, they were more likely to have children with someone who lived nearby. Over time, this led to people having a closer relationship with their neighbors than with people who lived further away.

So back to that tube of saliva you sent to the ancestry testing company. They pull your DNA from the cells in your saliva and then they look at what’s in your DNA at hundreds of thousands of places.

Once they have the DNA code on these sites, they can compare your DNA to a database of thousands of other people whose ancestry is known. They will then see which group your DNA matches!

In some cases, parts of your DNA may match with one population and other parts with another. This is what happens when you have ancestors from different parts of the world.

From the several spots in the DNA that the ancestry test analyzes, the total amount of DNA corresponding to each ancestor is counted and given as a percentage. For example, if you are 30% Moroccan, this means that 30% of your DNA specifically matches the DNA of other Moroccans in the company’s database.

Remember that ancestry tests only look at a very small percentage of your DNA at first. This means that, for example, a 30% match with Moroccans is still a very small fraction of your entire DNA code.

In general, it is not difficult to determine the exact continent (eg European or Asian). Ancestry assignments also tend to be more accurate for well-studied populations such as European populations.

In order for your ancestry to be correctly assigned, your ancestors must be represented in the database that the company uses as a reference. They can’t figure out that your ancestor is Maltese if they don’t have someone from Malta to compare them to!

Reference databases contain many people whose ancestry and genetic code are known. The company then compares your DNA to everyone in its database. They will reveal which group (or groups!) you fit best. A few things can be limiting here:

As you can see, there are several limitations that can lead to inaccurate results. In general, however, broader estimates of continental origin should be fairly accurate.

Origin is only a small part of the bigger picture of who you are. An ancestry test will tell you where your ancestors came from, but it won’t tell you about their culture and experiences that may have been passed down from generation to generation.

For example, you may find that your ancestors are mostly Chinese. But that doesn’t tell the story of how your great-great-grandparents got involved in a small Indonesian community and passed down those traditions and culture to you. On the other hand, you could have ancestors from a small Greek community in Italy. Although you always thought your ancestors were “Italian”, your ancestry will show that you are Greek.

Our history is complex and varied. A pedigree test can be fun and interesting, but we cannot expect a perfect picture from it. There are limitations on provenance tests, so colors don’t always come out right. At the same time, it is only a small piece of this larger puzzle of who we are.

How Accurate Is Ancestry Dna?

Margaret Antonio When this answer was posted in 2018, Margaret was a Ph.D. candidate in the Department of Biomedical Informatics, studying population genomics in Jonathan Pritchard’s lab. She wrote this answer while attending the Stanford at The Tech program. Millions of people took DNA tests over the holidays, and when the results finally start rolling in, many of you will be checking out the ethnicity news for the first time – 39% of this, 22% of that, 2% something completely surprising…all of which can be very exciting.

The answer is a resounding no. While your results certainly contain truths, accepting an ancestry report without further interpretation will often lead you to confusion and incorrect assumptions about your family history.

Despite feeling completely lost when they first see the results, many never question them. They simply assume that DNA is always correct (how could it not be?), or perhaps they are unsure how to dig deeper to resolve discrepancies. Others will ignore the confusing message entirely – assuming there was an error.

Ancestry Dna Has Updated Its Ethnicity Estimates Again

Fortunately, however, there are tips and tools that can help you understand your results in the right context and create a more accurate view of your genetic history. This article explores some of them.

Many of you who have received your ethnicity percentiles from companies like AncestryDNA, Family Tree DNA, or MyHeritage DNA will be surprised to find that your makeup is not at all what you imagined. You may be missing regions you expected to find (such as Irish or Italian), or have others you didn’t expect at all (such as a large number of the British Isles or some Jewish ones).

If you’ve tested (or uploaded your raw DNA to) multiple companies, you may be even more confused because your results will likely vary quite a bit from test to test. You may be wondering which of these DNA tests is the most accurate? Which results should I trust? Am I really 36% Scandinavian?

Confusing results can completely change your perspective on your ancestral past or make you question your roots or family history research. And because ethnicity percentages can seem so absolute, you might be tempted to take them at face value. Or, if they conflict with your existing family history, you may be tempted to reject them. Both of these reactions are actually quite common.

Disclaimer – DNA results can throw up serious surprises, so while educating yourself on how these tests work can help you make sense of confusing results and inconsistencies, some unexpected information may actually be related to unknown facts about your family history.
