The spit is for one of the home genetic-testing kits I’m sampling. A growing number of these kits (brands such as 23andMe, DNAFit, Thriva, MyHeritage DNA, and Orig3n) promise to unlock the mystery of your genomes, variously explaining everything from ancestry, residual Neanderthal variants, “bioinformatics” for fitness, weight loss and skincare, to more random genetic predispositions, denoting, say, the dimensions of your earlobes or the consistency of your earwax.
It’s easy to do these tests; it’s usually just a case of collecting your own samples at home, filling in short, basic questionnaires, posting the packages, and then logging on to interactive websites for confidential results (all the kits I tested used outside laboratories). With an array of price ranges and options, from one-off DNA-blitzes to targeting specific health areas, to fitness/wellness tracking, it’s no surprise that these kits are proving to be very big business and the field is primed to get even bigger, with a global market estimated to be worth around £7.7bn by 2022.
Miscellaneous, fun DNA tests: On the not-so-serious side of at-home DNA testing, there is a company that offers wine recommendations based on your genes. Vinome is part of the Helix marketplace. It creates a personalized taste profile for you based on your genes and offers a curated list of wines you can buy through the service. If you buy and rate the wines, Vinome hones in on your preferences and matches you to new products.
There are mixed reactions to the use of ancestry DNA databases in criminal cases. On one hand, the rise of readily-available DNA information for millions of people has led to the arrests of several suspects related to long-cold cases, including the arrest of the Golden State Killer. On the other hand, law enforcement accessing private databases of genetic information from consumers raises several questions regarding privacy and ethical issues.

Bill Newman, professor of translational genomic medicine in the Manchester centre for genomic medicine at the University of Manchester, and chair of the British Society of Genetic Medicine, says that such tests in this context simply don’t make sense and that, usually, telomere testing would only be used in in-depth studies of ageing and diseases associated with ageing. “There’s some really brilliant work going on, by some of the best biologists in the world,” says Newman, citing Elizabeth Blackburn, who won the 2009 Nobel prize for medicine for her work on telomeres. “But there’s no evidence whatsoever that measuring a person’s telomeres gives any indication about their health – or beauty, intelligence, or anything else that might be listed on these sites.”
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.
When we speak, co-founder Hamish Grierson describes Thriva as “a lifestyle brand with medical-grade testing at the back end”, an opportunity for “people to see themselves as consumers rather than patients”. Grierson gives examples of people who have benefited from Thriva testing, sometimes picking up early on serious issues. As for alarming people, Grierson says that Thriva has on-site facilities to discuss results and is intended to be “complementary to the NHS” rather than replacing it: “If there are questions we can’t answer, we’re very clear that people should pick it up with their GP.”
McCartney says that anxious people often contact her, saying they wished they hadn’t done the tests. “These companies often say that it’s worth it for the helpful advice. But I can give you really good advice right now without seeing a single test result: be active, have lots of social networks, do work you enjoy, try not to smoke or drink too much, don’t be overweight or underweight, eat lots of fresh fruit and vegetables. Nobody needs to get tests done to get that kind of basic lifestyle advice.”
For about $20 less than other DNA ancestry services, MyHeritage DNA gives you an ethnicity estimate and access to DNA matches. It’s true value, however, lies in its free raw DNA uploads. If you’ve already taken a test with another company, MyHeritage lets you upload your raw data to its database for free. This feature is particularly useful if you’re looking for lost relatives, as you can pay slightly more for one test with Ancestry or 23andMe, which have larger databases, but still access MyHeritage’s database as well, which has 1.75 million users as of October 2018. With a 16-day turnaround, MyHeritage DNA was one of the first companies to send back our test results, but I found the contents of my ancestry report to be a bit off, especially when compared to my geographic ancestry reports from other companies. I was born in Korea and therefore expected at least a little of my Korean heritage to make it onto my ancestry map, as it did with other services, but MyHeritage didn’t report any Korean heritage. Instead, MyHeritage DNA reported I that I’m of Japanese, Chinese and Vietnamese, and Mongolian descent. As I was looking for a reason to explain the discrepancy between tests, I discovered that there are large swaths of the map not covered by any of the service’s ancestral regions. The Korean peninsula is one of those areas, as are southern regions in South America, Africa and almost all of Australia and Russia. The oversight seems odd because MyHeritage could have easily included these missed areas inside a larger, generalized region instead of completely omitting them.

Pet DNA tests: Companies like Embark, Wisdom Panel and many others offer genetic health risk screenings, trait analyses and breed percentage information for dogs. These canine ancestry tests allow you to confidently state that your mutt is part Irish wolf hound and give you key information about your pet’s heritage for insights into potential health issues. For example, if you find out one of your rescue dog’s parents was likely a purebred boxer, you could speak with your vet about breed-specific needs. Basepaws DNA CatKit promises information about your cat’s breed and traits with just a hair sample, though it offers swab kits for hairless cats. The kit also tells you how closely related your kitty is to wild cats like lions, tigers and (bears, oh my!) ocelots.]
A collaboration between scientists, researchers and genetic experts from across the globe, Living DNA has offered ancestry tests since 2016 while parent company, DNA Worldwide Group, has been operating since 2004. Our focus has always been on providing the world’s best collection of British and Irish historical records and while we’ve investigated the DNA market for some time, we hadn’t identified a partner that could truly bridge the gap between genetic genealogy and traditional family history research. Living DNA’s focus on British and Irish DNA makes them our perfect partner.
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. This report tells you interesting information, such as that your DNA relatives are 32 percent more likely to own a cat or 11 percent less likely to have lived near a farm when they were young. DNA Passport by Humancode offers information about more than 20 physical traits, from appearance to grip strength. Ancestry DNA recently added its AncestryDNA Traits upgrade for $10, and it lets customers who have already taken one of its tests unlock information about 18 genetically influenced traits, including bitter taste perception, freckles and cilantro aversion.
Although FamilyTreeDNA is the only DNA testing company openly working with law enforcement, other DNA companies don’t necessarily keep your DNA information private. Many direct-to-consumer DNA testing companies sell your data to third parties. For example, 23andMe shares customer data with pharmaceutical giant GlaxoSmithKline, which uses the information to develop medical treatments. In this case, you can opt out of having your DNA information used for research, and the data is shared only in aggregate.
I am not sure how Ancestry get their results. Mine is 49% British and 49% German. This means one of my parents must have been British and the other German. I moved to the UK 15 years ago. But both my parents where German as where my 4 grandparents and my 8 great-grandparents. It seems to me they have rolled the dice and assumed that if you send a sample from the UK you must have British ancestry. No science behind it at all. I could have gone to the oracle at the fun fair.
An ancestry DNA test uses a saliva sample to determine which areas of the world your DNA can be traced back to. DNA kits have become very popular during the last few years. This has led to many people having numerous questions. You may be wondering if your genetic information will be used for research or sold and how this impacts your privacy. You may also be concerned regarding the accuracy of this test or have numerous additional questions. The first thing you must realize is the question of your DNA is complex and there may not be a simple answer. The majority of people in the world have DNA from numerous different regions. You may perceive this combination as unique or you may see it is odd. Either way, you need to be open and prepared for a surprise.
On all platforms except for National Geographic, you can initiate a search for relatives, though some services let you upload your National Geographic results for further analysis. The software continually searches for DNA matches as more people share their results. This feature may be useful if you're building a family tree or looking for relatives you've never met; otherwise, it may more of a nuisance. You can opt in or out at any time, and the DNA service doesn't share your contact information. Relatives can message you through the software, though. If you already use genealogy software, you may be able to download your results and upload them into your preferred program. Otherwise, AncestryDNA and others featured here have family tree software that you can easily link.
DNA Diagnostics Centre offers a range of exciting ancestry testing services. Whether you’re looking to discover the origins of the maternal or paternal side of your family or you wish to determine your genetic profile and learn how much ancestral DNA you have from European, African, indigenous American or Asian peoples, we have the right test for you.
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.
The 23rd pair of chromosomes is comprised of sex chromosomes – X and Y chromosomes that determine whether you’re male (XY) or female (XX). Traits like red-green color blindness, male pattern baldness and hemophilia are specifically linked to X or Y chromosomes and are called sex-linked characteristics. All of those examples, and most other sex-linked traits, are X-linked and more common in males, who only have one X chromosome. Many DNA tests isolate Y DNA in males to show consumers their paternal haplogroup. Since the Y chromosome is directly inherited from father to son, it is possible to trace direct paternal lineage for many generations.
AncestryDNA is a cutting edge DNA testing service that utilizes some of the latest autosomal testing technology to revolutionize the way you discover your family history. This service combines advanced DNA science with the world’s largest online family history resource to predict your genetic ethnicity and help you find new family connections. It maps ethnicity going back multiple generations and provides insight into such possibilities as: what region of Europe are my ancestors from, or am I likely to have East Asian heritage? AncestryDNA can also help identify relationships with unknown relatives through a dynamic list of DNA matches
In our tests, we did find consistency across our results on the continental level. For example, my ancestry is exclusively East Asian, but 23andMe breaks it down into 80 percent Korean, 10.5 percent Japanese and 0.8 percent Chinese, with the remaining 8.7 percent in broader categories. However, Ancestry reports my DNA as 98 percent Korean and Northern Chinese, with only 2 percent Japanese. National Geographic places 85 percent of my ancestry from Northeastern Asia and 14 percent from the South China Sea region, with my DNA most closely matching the Korean and Japanese reference populations.
Although the project states that most participants won’t receive any useful information, patients will be told if something is found in their genome that is relevant to the treatment, explanation or diagnosis of their condition. They can also choose to learn if they have a genetic risk factor for another disease, such as the BRCA1 gene mutation that can cause breast cancer. Genomics England will only look for risk factors that are linked to a disease that can be treated or prevented. Untreatable conditions, such as Alzheimer’s, are not looked for.
