MyHeritage DNA is the newest kid on the block and, while their database is still growing, it is comprised of people who have tested from all of the other three testing companies (this is thanks to their free DNA upload offer). In addition to this, they have shown a clear commitment to concerns and requests by their users by promising to provide advanced tools in the future and by creating an open and optional consent policy for use of DNA data. They also offer the ability to tie in with a large database of family trees and records. We think this test has a lot of promise if they continue to respond in this positive way to users.
A friend of mine knew I had been working on my family history and bought me an AncestryDNA kit for my birthday. My results were surprising to say the least. I discovered I’m 35% Native American, 5% African and 29% from the Iberian Peninsula. This has drastically broadened the way I think about my identity and heritage. I feel connected to those parts of the world now and I’m excited to see how far back our records can go.

The SGM Plus system of DNA analysis targets ten loci, each of which contains two alleles. These are the “short tandem repeats” that vary between individuals. In addition, a further locus is targeted that acts as in indicator of the sex of the donor. A “full” DNA profile is one in which all of these loci have produced a reliable and reportable result. Occasionally, the processes used to target some of these loci fail, resulting in an incomplete or “partial” DNA profile. The most common reasons for such failure are either that a very small amount of DNA was present in the sample, the DNA may have become degraded, or that substances may have been present in the sample that may have inhibited the analysis process. Depending on the degree of success of the DNA analysis, the match probability calculated from a partial DNA profile may be reduced below the 1 in 1 billion that would be obtained from a full profile.

As well as showing you which ethnic groups you’ve inherited your DNA from, autosomal DNA tests can also be used to find living relatives and build your family tree. Many people attempting to build their family tree will often make breakthroughs in their research when they combine a DNA genealogy test (such as an ethnicity test) with traditional genealogical techniques.
Note that DNA testing isn't the only kind of kit that collects physical evidence from you these days. Ubiome is one noteworthy example. The service evaluates your microbiome—basically the bacteria that live in and on you. In our review, we took its gut biome test, which required our intrepid reviewer to send in a poop sample (insert poop emoji here).
For these reasons, mapping segments of your autosomal DNA to whole continents can be determined with a high level of certainty, but when you try to attribute these segments to specific tribes, regions or even countries, the certainty decreases. This is why some genetic ancestry companies will attribute a proportion of your DNA to areas such as ‘Eastern Europe’ or ‘Southern Asia’, instead of to specific countries.

Specific tests for your father’s family include ‘Y-DNA’ tests which focus on the ‘Y chromosomes’ in your cells’ nuclei, passed down from father to son. Specific tests for your mother’s family include ‘mtDNA’ tests which report on a subset of DNA found in the ‘mitochondria’ (your cells’ energy factories), passed down from mother to son or to daughter.
It is very important that you take the time to read the privacy policy, terms and conditions and consent forms associated with any DNA test you take or any site you choose to upload your data to. While FTDNA has a proven track record of protecting the privacy of its users, there have been serious concerns over how AncestryDNA and 23andMe have used data in the past, as well as how they may use or sell your data in the future. Please read this article from Roberta Estes for more information on this issue. MyHeritage states that their consent form (that would allow sharing or selling of your results in aggregated data) is optional.  You can read more about that on The Legal Genealogist, who compliments MyHeritage DNA on their policy and openness.
Living DNA offers the best biogeographical ancestry analysis on the market for people with British ancestry and they are the only company to offer regional breakdowns. With the inclusion of Y-DNA and mtDNA haplogroup information, this is a good all-round test for someone who wants an overview of their genetic ancestry. The test cannot currently be used for genealogical matching, though an autosomal matching service is promised for the future. As a late entrant to the market, Living DNA will start with a smaller database though the test is more likely to appeal to people in the UK, especially those who feel safer keeping their DNA data in Europe.
Getting the most out of your AncestryDNA results requires a bit of work, as the DNA test works best in concert with the site’s other available resources. You can use the DNA service without creating a family tree, though the results are much less interesting. Ancestry uses information gleaned from its user’s DNA and family trees to create compelling stories about your family’s recent history and migrations. Testers with European roots could trace their family’s movements across the Atlantic and see what stops they made on their way across the U.S.

Whether it’s an autosomal test, a Y-DNA test or an mtDNA test, virtually all providers use the same science. Some providers offer an ‘off the peg’ solution such as Ancestral Origins™ or AncestrybyDNA™, so if you’re interested in these you should shop around for the lowest price. Most providers offer a test that interprets and presents the results in a unique way, so if one of these catches your eye, look for examples of how the results are presented on their website before you buy.


DNA tests give you an educated estimate of your ethnic makeup and help inform genealogical research by verifying existing family trees and informing future avenues of investigation. Additionally, there's a possibility you'll find living DNA matches - distant cousins and other relations - who could share their family history with you to build a bigger picture of your family tree.
A genetic counselor, a healthcare professional with special training in genetic conditions, will be able to answer your questions and help you make an informed choice. We recommend that you speak with a genetic counselor before testing, and also after testing to help you understand your results and what actions you should take. This is especially important for health conditions that are preventable or treatable.
To prepare to take a cheek swab sample, you also have to refrain from eating for about an hour before. Swab kits generally contain more components, including one or two swabs and containers to protect the used swabs from contamination. We found it easiest to organize all the pieces first, to prevent any fumbling with a sample collection swab in hand. Some cheek cell kits put a stabilizing liquid in the sample containers, which required extra caution to prevent spilling.
Generally speaking, those people who have tested with FTDNA, AncestryDNA or MyHeritage DNA have done so for genealogical purposes (even if it is only curiosity about their family’s past) so the response rate from contacted matches is fairly decent. Oftentimes matches are open to being contacted by relations and are eager to compare trees. This is, of course, not always the case, but we have found it to be true for the most part.
I hope this helps to clear things up. Ancestry DNA testing is not an exact science, and is limited by the fact that we don't inherit the exact same DNA our parents had, meaning that with each new generation, old DNA is lost. Ancestry tests can provide estimations of our genetic ancestry, and though they are improving all the time, they can't tell the whole story of our heritage.
Both men and women can take mitochondrial DNA tests (because we all possess mitochondria in our cells), but it’s worth noting that women are unable to take Y DNA tests as they do not possess a Y chromosome. If you’re female and you’d like to learn more about your paternal lineage, you can ask a close male relative to take a Y DNA test on your behalf – read our article about Y DNA testing for more information.

In addition to showing geographic ancestry percentages, some direct-to-consumer DNA tests also include insights about physical traits like hair and eye color. With 23andMe, this trait information is mostly available in the upgraded Ancestry + Health kit, but some interesting tidbits can be found in the Your DNA Family report, which is available if you opt to participate in the DNA Relatives service. 
Consult a doctor on any health data: Cancer. Leukemia. Heart disease. Alzheimer's. There are a lot of scary afflictions out there, and your DNA testing may well indicate which ones to which you are genetically predispositioned. But the data from DNA testing exists in isolation. You should consult your doctor to explore the data from any of these tests. They'll help you determine how to implement any lifestyle changes or followup testing as a result, if it's worth doing so.

When a sample of biological material contains DNA from more than one person, this can result in a “mixed DNA profile”. In such profiles, there may be a reduced amount of useful information regarding whether or not a specific person could have contributed to this sample. This could be because the contributors may share one or more DNA alleles, resulting in the masking of the DNA of one person by that of the other.

Offering DNA test kits and a range of online subscription services, MyHeritage says that its database includes more ethnicities -- that's 42 -- than any other major testing service. The free 14-day trial will let you poke around the company's massive online database which includes 3.5 billion profiles in addition to information about over 100 million subscribers and their collective 46 million family trees. 
Looking at your raw DNA file might not give you any useful information unless you’re looking for a specific marker. You can also upload the file into a third-party DNA databases for information or results beyond what’s available from your testing company. This process is not without risks, as your DNA testing company only ensures the security of your personal information in its own environment. Once you download the file, you’re responsible for the file’s security. However, uploading your raw DNA to a third party database isn’t inherently unsafe — just be cautious.
Because it is a genetic condition, FH is present at birth, meaning most people with this condition have high LDL cholesterol levels from a young age. Since many people with FH show no physical symptoms, this condition is typically diagnosed with a blood test for cholesterol. However, some people with FH may not be diagnosed until after experiencing symptoms related to early heart disease, including chest pain or heart attack.
As a postscript, I eventually end up having an interesting chat with Titanovo about my “bioinformatics” (distilled from my 23andMe data). One of the first things I’m told is that my eyes are green (they’re brown). However, the bioinformatics got my skin type and frame/weight generally right and had interesting (albeit occasionally generic) things to say about exercise, diet, goals, steering clear of too much sugar and so on.
The results of mixed DNA profiles may therefore provide reduced match probabilities when compared with non-mixed profiles. It may be possible for a scientist to be able to assess the relative amount of DNA contributed by different donors in a DNA mixture. If one person has contributed a clear and distinct majority of the DNA detected, that part of the profile may be referred to as the “Major Contribution”.

Generally speaking, those people who have tested with FTDNA, AncestryDNA or MyHeritage DNA have done so for genealogical purposes (even if it is only curiosity about their family’s past) so the response rate from contacted matches is fairly decent. Oftentimes matches are open to being contacted by relations and are eager to compare trees. This is, of course, not always the case, but we have found it to be true for the most part.
When my results appear, they show nothing bad. If anything, it’s anticlimactic: cholesterol, vitamins, liver proteins and the like are all in the normal range, with only ferritin (iron stores) slightly high, with a recommendation to go easy on any iron supplements. My problem with the baseline test is that, unlike Thriva’s other products, clients are supposed to have one every three months to keep track, but would I really want (or indeed need) to do such a test so regularly?

FTDNA has the most advanced tools for easily analyzing cousin matches as of now, although it is possible that MyHeritage DNA may catch up. They seem very eager to please customers at this point. FTDNA does fall short when it comes to the ability to sync with developed family trees however. This is certainly not intentional on their part, they have developed some great tools for this purpose, but FTDNA (unlike Ancestry and MyHeritage) does not provide record searches or an online family tree program for the purpose of genealogical research. For this reason they are inherently limited in this regard.


There is one really, really important thing to know about this estimate, however.  Each child inherits 50% of their DNA from each parent.  That means that 50% of their parents’ DNA does NOT get passed down to the child.  This can mean that a child of a 100% Eastern European person will only show 50% Eastern European DNA, and their grandchild will only show 25%, and their great-grandchild 12.5% – in a perfect scenario.

When it comes to proving a biological relationship between a British citizen and a family member living abroad so that they may immigrate, DNA testing can greatly strengthen the case. However, DNA evidence alone does not guarantee a successful immigration application. If you’re considering taking a DNA test for immigration purposes, we recommend you take legal advice to ensure it’s used in the best possible way.
