Despite feeling lost when they first see the results, many people never question them. They just think DNA is always right (how could it not be?) or they don’t know how to dive deep enough to resolve inconsistencies. Others simply ignore the ambiguous report altogether – assuming that a mistake has been made.

But luckily, there are tips and tools to help you put your results into perspective and gain a clearer picture of your genetic past. This article explores some of them.

Many of you who receive a racial percentage distribution (composition) from companies like AncestryDNA, Family Tree DNA, or MyHeritage DNA are surprised to learn that your makeup is not what you thought. Maybe you’re missing areas you’d expect (like Irish or Italian), or there are others you didn’t expect (like the British Isles or some Jews).

If you’ve tested with multiple companies (or uploaded your own raw DNA), you can get even more confused because your results will vary greatly from test to test. You may be asking yourself, which of these DNA tests is the most accurate? What results should I trust? Am I really 36% Scandinavian?

Confusing results can completely change your perspective on your ancestral past or cause you to question your roots or family history. And because racial percentages can seem so absolute, you might as well believe them. Or you may be inclined to reject them if they conflict with your existing family history. Both of these reactions are very common.

Disclaimer – DNA results can lead to serious surprises, so explaining to yourself how these tests work can help you make sense of confusing results and inconsistencies, and some unexpected information. may be related to the facts.

A non-parental event (the father is not the biological father), covert adoptions, and outright mistakes in family history (thinking your family is from an area or group that you are not) are readily available. . Sometimes these things can be very obvious when the test results come back, sometimes they are hidden, but they will definitely cause you to get tested again.

But you shouldn’t assume that your results contain surprises, confusion about your past, or mistakes. They are often due to how you read your report.

The key to understanding all of this is understanding how your race grades are decided. Knowing how these tests work can help you better determine which bits should be investigated more closely and which bits are based on what is known about your family history.

Let’s start by understanding why your results may not fully reflect your lineage. After all, it’s DNA, shouldn’t it be silly?

How Your Dna Test Could Send A Relative To Jail

The problem with “errors” in DNA genealogy reports has nothing to do with your actual DNA. Rather, it depends on how the companies that provide your results interpret and present your DNA. Each of these companies uses software to compare your data with a sample population they have in their database – and that shows the composition of the sample population, their presence (or lack thereof), how they compare to each other. may be confusing and the company chooses to provide you with this information. This can be shown by looking at several tests from different companies for the same person.

Below is an example of inconsistencies that can be seen from test to test for the same individual. Note the difference in population names and percentages.

There are some big differences here. A person’s DNA has not changed from test to test – what has? Which of these results should be trusted?

The truth is that all major testing companies are doing their best to give you the most accurate results. Although they all have their weaknesses, it is in their best interest to provide their clients with results that accurately reflect their lineage. Every testing company wants to be the best choice. It’s just good business.

But these companies want to provide you with simple and easy-to-understand results that you can easily read, understand and share. That’s why a lot of effort has gone into creating attractive charts, easy-to-understand population groups, and maps that show at a glance where your ancestors are believed to belong.

In emphasizing this simplicity, the complex process of presenting your genetic data should be limited, and more detailed information that would help you better understand your results is often omitted – for example, a detailed definition of population groups, how populations relate to each other. explanation or science of matching. determines how interest is calculated.

Population is not always what it seems. When you get your results and start looking at percentages, it’s easy to look at the population and make assumptions about that population. But to understand what that means in the context of the test you’re running, you’ll need to get some information about the population.

The best way to do this is to carefully read the specifications provided by the testing company to fully understand the geographic boundaries, included and excluded regions and people, and the information that affects that population.Historical events. Some tests do a better job of providing this information than others, but all provide some level of access to this information.

Ancestry Dna Tests Don’t Always Find What We Expect

To illustrate how vague populations can be and how misleading their names can be, we can review the three reports above. About 25% of the people featured in this test have known ancestry from the Netherlands (and closely related areas such as Germany, Belgium, etc.). This means that according to the genealogy, 25% of the ancestors are from that area because the grandfather and their ancestors are from that area. However, since we did not get exact percentages from each grandparent, the actual amount may be slightly higher or lower genetically.

25% of our ethnic composition is from this region. However, if you look at the images above, we don’t see anything close to those numbers in any of the tests.

The first thing we noticed is that the Netherlands and its surrounding areas have no population of their own. They are added under different names depending on the test. So, we should not expect to see “Holland” or “Germany”. Indeed, many of the sample populations we seek simply do not exist because they are not genetically unique enough (given our current analytical tools and sample sizes) to allow for distinct “populations.”

Instead of Family Tree DNA, it shows Holland and Germany in the region marked Western and Central Europe as a subcategory of Europe and gives a percentage of 13%. This is less than expected, but we can see that Scandinavia and the British Isles are also included. Given that both of these populations are larger than we expected, we can assume that some of our West/Central Europeans are actually showing up as Scandinavians and/or British Isles. A closer look at the map shows that the population of the British Isles overlaps significantly with our area of ​​interest (the Netherlands).

Although this is not ideal, we must keep in mind that many populations overlap in their genetic similarities. The genetic populations used to determine your percentage are very closely related and can be difficult to tell apart.

And it affects more than your unique makeup. A person with ancestors in Western Europe, Scandinavia and the British Isles, one percent dominates the others and shows a lot.
