Places You Can Upload Dna for Free

Do you desire to know if the ethnicity approximate that you received from your DNA test results is accurate?  Did you see an ethnicity reported that surprised you?

Most companies say that the ethnicity estimate that they provide you with tin can go back as far as 500 years, or even a trivial more.  Information technology seems natural to wonder if it possible for them to study a consummate ethnicity report roofing such a long fourth dimension menses.

In this post, y'all will acquire:

• how they decide your ethnicity
• how far back ethnicity tests can really achieve
• which ethnicity estimates you can trust

Hint:  About companies utilise the discussion "estimate" for a reason, and if they don't employ the give-and-take "judge, they should.

In the spirit of full disclosure, I am a huge fan of Dna testing and I wish everyone would consider doing it.   It can be extremely useful for understanding where your family came from, finding new family unit members, finding biological family, and researching your family tree.

I feel that it is of import for people to know what they are really getting when they get their ethnicity guess, even so.

Agreement ethnicity gauge accuracy

In lodge to really know whether your report is authentic, you should know a niggling bit about how they determine your ethnicity, and how far back into history the DNA test can "achieve" using electric current technologies.

How they determine your ethnicity using Dna

Each company uses a slightly different method but the bones procedure is the following:

• They collect DNA samples from people whose families have lived in specific geographic regions for generations
• Using the nerveless DNA samples, they create a "reference panel" (the terminology used might vary from company to visitor)
• When y'all submit your examination, they compare your DNA to the reference console
• They give you your ethnicity estimate and Dna matches (unless your company doesn't offer matches as a feature)

Every bit you might be able to judge based on the procedure that they utilize to know your ethnicity, the output is only as good equally the input.  The near important aspect of the process is that they take a large collection of DNA samples that accurately represent the people who live in that region.

There are two means that this can go wrong:

• The sample database isn't large enough
• Difficulty finding and verifying DNA from people whose families accept ever lived in the same area

The biggest challenge is getting a database full of Dna samples that is large enough to be useful.

Additionally, in club to add people to the sample database, yous would need to exist absolutely 100% sure that the person's family tree is accurate.  In some parts of the world, especially where records are more scarce than others, I wonder how piece of cake this is to do.

How far back ethnicity estimates can reach

Assuming that the company has a really great database, does this mean that they volition be able to tell you all of the ethnicities that your family unit had reaching back 500 years or so?

The answer to this:  no.  Sure, your ethnicity estimate volition be able to tell you some of your ethnicities reaching back 500 years.

Well-nigh of the ethnicity that is reported will exist more recent, however.  In lodge to understand why, y'all have to know a petty bit almost how Deoxyribonucleic acid is inherited.

The type of DNA tests that we are talking well-nigh are called autosomal Deoxyribonucleic acid tests.

These tests simply test our autosomal chromosomes, equally opposed to our sexual practice chromosomes, which incorporate different information.  Autosomal Deoxyribonucleic acid is inherited randomly from each parent (50% from each one).

Every generation, there is some DNA that doesn't get inherited:

(feel complimentary to download and share this image!)

The example in the epitome above is in a perfect scenario, where in each generation, exactly 50% of each ethnicity is inherited.  In that location is ever some left behind.

If you imagine that determining which Dna a child gets is like reaching into a basket of bits of DNA with your eyes closed, there is no mode to know which Dna you lot'll grab.

A more realistic scenario would mean that if there was only a pocket-size amount of a item Dna to cull from, like 5-10% Central Asia, for example, it is perfectly reasonable to expect that none of that ethnicity was inherited by the child.

In the basket example, imagine that in that location are 100 pieces of Dna.  What are the odds that yous would grab whatsoever of that five-10% DNA from Central Asia?

The smaller the percentage of ethnicity, the bigger the adventure that it gets left behind and not passed down to you.

Conversely, it tin can happen that y'all randomly inherit all or most (more than the average of 50%) of the Deoxyribonucleic acid of a particular ethnicity from your parent.  In the handbasket example, once more, it can happen that yous are "lucky" and grab all of the DNA bits that friction match Fundamental Asia.

Additionally, there is one important point that I would similar to make:  If you had a great-great grandparent that was 100% of a particular ethnicity, it is statistically possible to accept inherited zippo of their ethnicity.

This is because information technology is possible to share admittedly no DNA with a great-great grandparent.  The further back you go, the more than likely it is that you share no DNA with them, therefore inherited none of their ethnicity.

Thus, there are 2 consequences of reading besides much into our ethnicity estimates:

• Nosotros might completely miss an ethnicity that belonged to one of our ancestors, leading united states of america to believe that our family unit tree or what we take been told nearly our family history is incorrect
• If we inherit a larger percent of ethnicity than is usual (more than fifty%, for instance) it can pb us to believe that the antecedent from that region is closer in generations than they really are.  Sometimes this can besides lead us to believe that we have a underground or mystery in the family.

Which companies provide the almost accurate ethnicity estimate?

The top three DNA testing companies, Ancestry DNA, Family unit Tree Deoxyribonucleic acid, and 23 and Me, provide estimates that are every bit authentic as they can be, because that information technology is incommunicable to provide a 100% accurate ethnicity report.

Why is it incommunicable?

• Because of the way Deoxyribonucleic acid is inherited, you lot can take more, less, or none of the ethnicity that you lot expect to find
• Even if someone's family has historically lived in Britain, for example, they may have ethnicities from other places.  So if you know that your bully-grandfather was a British immigrant, it doesn't mean that he had 100% British Deoxyribonucleic acid.
• For a region similar North and S America, people who accept indigenous ancestry will typically merely bear witness "Native American", since the technology is non withal good enough to isolate specific regions.

If y'all are because doing a DNA test with a company that I did not list to a higher place, y'all should know that you lot will have to have your ethnicity report with a grain of table salt and exercise your own research to run into if it lines upward with your family tree.

Is at that place a style to get an alternative ethnicity estimate?

If you are unhappy with your ethnicity estimate, you are in luck.  Yous can merely get a different 1!  In fact, there are several ways to get a different estimate which might (or might not) show you what you are looking for.

In that location are various legitimate websites which allow you to upload your raw DNA file and get ethnicity estimates, equally well equally additional Dna matches.  This can sometimes be helpful because each company or researcher uses a different reference population to compare with your Deoxyribonucleic acid.

While your judge should exist largely similar to your original company's approximate (unless you test with a less reliable or experienced visitor), you might be able to find something helpful in your alternating DNA gauge.  Here is a list of places you can use to upload your DNA, some free, some not:

• Gedmatch (free)
• Gedmatch Genesis (free)
• Family Tree DNA (free upload and matches, $19 for unlocked ethnicity estimate and chromosome browser)
• My Heritage DNA (free)
• Dna Country (free)

If yous want to know fifty-fifty more than about your family'due south ethnicites, you should consider having your parents (or siblings, if your parents can't or won't examination), aunts, uncles, or even grandparents do a test.

They volition each have slightly different ethnicity results that can help y'all get a more complete movie of your family history.

Decision

With all of the information I provided, y'all might be wondering why anyone even does these Deoxyribonucleic acid tests anyway?

Like I mentioned before, an ethnicity estimate isn't going to tell you everything near the ethnicities of all of your ancestors going dorsum 500 years, just it is going to tell you a lot most many of them. This can be an extremely helpful snapshot of your family's ancestry.

Accept you lot establish anything unusual in your ethnicity guess?  What was your experience?  I would love to hear from you in the comments!
