First, I must admit that I am a genealogy geek. Ever since I was a child, I have always been interested in researching my ancestors and managed to trace 7 generations of my ancestors through the archives. Being a curious genealogist, I wanted to try the best DNA test.
Most Accurate Dna Ethnicity Test
Unfortunately, I was quite disappointed with the results, so I decided to test with other ancestry DNA testing companies. The DNA test results showed completely different relationships and regions, so I decided to discover the truth about these discrepancies.
A Home Dna Kit For £130
After 7 months of hard work and numerous consultations with experts, I have completed an in-depth study that shows what is the most accurate and best DNA test kit on the market right now. I have received many questions from readers, which I have tried to answer at the end of this post. My goal was to use everyday language. But if you have any questions, send them by email.
To date (2022), more than 30 million people have tried to learn about their ancestry and family tree through DNA testing, but it has brought more confusion than clarity. I’m trying to clear the fog.
According to my ethnicity calculations (based on principal component analysis), my genealogy and database size review, currently (2022), the best DNA testing company:
The research consists of three areas. One of them – probably the most important – is to compare my genealogy with the results of the DNA test kit: which DNA test is more accurate?
Best Ancestry Dna Tests 2023: Top Kits For Exploring Your Family History
All things considered, I think AncestryDNA is the better choice. If you’re looking for relatives or family members, it’s also worth checking out 23andMe, as both companies have fairly large databases of DNA matches, and the overlap between their databases is unlikely to be significant. See my in-depth 23andMe vs. AncestryDNA comparison.
Another big part of DNA testing services is maternal and paternal health. When it comes to genetic predispositions, many things are known from science. There are certain genes that make people more vulnerable to certain diseases like cancer, diabetes, high blood pressure, Alzheimer’s etc.
If you know about them, you can act in time to control the disease. Beginning October 31, 2018, the FDA will allow direct-to-consumer tests to diagnose a number of genetic health conditions.
The 4 Best Dog Dna Tests Of 2023
Through endless hard work, we’ve collected all the talents, traits and health vectors from eight of the most popular DNA health test kits:
Ancestry is one of the most famous genealogy companies. If you’re building your family tree, there’s no better company. Their database is large and their ethnic DNA results are the most accurate (according to my research).
For adoptees (who are looking for relatives), this is a great option because of the size of its database. Here is my in-depth AncestryDNA review.
The most accurate DNA test kits with the best price-value ratio. It’s also great for looking up relatives for adoptees. IMHO, the #1 service on the market in 2022.
Best Dna Test Kits
23andMe is one of the oldest companies in the DNA industry and started with healthcare DNA analysis. According to my research, the genetic health risk test is the most comprehensive. After some time it entered the market and its database is one of the largest databases.
MyHeritage started offering its services in 2016, so it is one of the youngest companies on the market. However, the price is affordable.
Recently it has started offering the best kits for health analysis. It allows you to upload raw DNA from other companies and search for relatives in their database. See my in-depth MyHeritage review.
FamilyTreeDNA’s customers and community are the smartest. If you want to learn more about genealogy, you can join their expert groups. It also has regular podcasts and support videos on DNA test kit tools, family history, ancestry, maternal and paternal lines, and other interesting genealogy topics.
Matriclan Test Kit
However, for a casual user, I find the platform and its tools too complex, and the test database of its ancestors too small.
The main disadvantage is that it provides Y-chromosome and mtDNA testing separately from autosomal. It’s also very expensive. See my in-depth FamilyTreeDNA review.
LivingDNA is the smallest home DNA test kit company on our list. Didn’t provide any information about their DNA database… I had to wait over 3 months for my results and their customer support is also very slow.
Since these are very important points and we have to trust the honesty of the company, I tried to make sure whether the data is accurate or not.
What You Can And Cannot Learn From Your Genes And Dna Tests
I checked how often their company name was searched on Google and compared it to the data that the companies themselves provided. Apparently they are telling the truth because there are similar numbers (search in brand and database size) between the two.
Our DNA strands provide every piece of information that defines everything about us. Basically, our DNA defines us. Also over time, our DNA determines the changes in us. A large part of our destiny lies in our genetics.
We inherit 50% of our DNA from each of our parents, half from our mother and half from our father.
It can also happen that a person inherits their grandparents’ DNA in a ratio of e.g. 20-25-25-30%, so that they inherit more from one of their grandparents than the others. maternal line
Which Dna Test’s Ethnicity Estimate Is Best?
This list shows that, viewed alone, we inherit very little from any distant relatives. Instead, our DNA is defined by the totality of our ancestors.
22 pairs of chromosomes are autosomal genes, while 23 pairs are sex chromosomes, which are different in males and females. I will give more details about this later.
By the way, it is interesting that the proportion of DNA that matches other people’s DNA is 99.9%. The reason for this is that it encompasses the entire function of the human organism, so the difference we see is actually 0.01% of the DNA (which actually differentiates us).
One thing worth knowing about these tests is that autosomal DNA testing can be done on both men and women. This test determines people’s ethnicity.
Ancestrydna Regions By The Numbers
As I mentioned above, this method compares the DNA template to other reference templates. Autosomal DNA testing helps assess ethnicity.
These tests compare a small piece of DNA to other DNA. Companies involved in research and estimation of genetic information analyze 600,000-700,000 single nucleotide polymorphisms and compare them with reference groups.
It should be noted that the selection of these reference groups is very important because any error will distort the results. In addition, it is important that the reference groups include as many samples as possible so that relevant and typical genetic markers for the ethnic group and region can be successfully detected by the testing company.
The twenty-third pair of chromosomes is the sex chromosome, which determines whether a person is male or female. Males have one Y and X chromosome, while females have two X chromosomes. These chromosomes make it possible to trace your maternal and paternal ancestors. Based on this information, it can be concluded that only men can do this type of DNA test. This image explains how the Y chromosome stem DNA test works.
A Man Says His Dna Test Proves He’s Black. He’s Suing.
Since the Y chromosome is passed from father to son, only one line of inheritance can be analyzed. However, a very long line of male descent can be traced through the paternal line. A great deal of interesting information can be discovered from Y-DNA. I encourage everyone to trace their own genealogy as some amazing revelations can be made.
The Y chromosome rarely mutates, so through genetic testing people can find out where their “ancestors” came from thousands of years ago. Haplogroups and reference populations can be created through mutation.
Mutated Y-DNA lineages are classified into haplogroups. Thus, haplogroups can be identified with specific (similar) regions and territorial units.
Of course, there are no homogenous haplogroup ancestors in any country because their populations have intermixed regularly throughout history. But as the map below shows, one can always identify a dominant group in each region.
