Even though we are all unique, most of our DNA is actually identical to other people’s DNA. However, specific regions vary highly between people. These regions are called polymorphic. Differences in these variable regions between people are known as polymorphisms. Each of us inherits a unique combination of polymorphisms from our parents. DNA polymorphisms can be analysed to give a DNA profile.
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.”
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.
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.
We provide expert advice and support in all aspects of DNA testing: paternity, maternity, siblingship, ancestry, DNA storage, and forensic consultancy. DDC has a large legal services client base and provides a comprehensive range of services which includes arrangement of sample collection, chain of custody, quality assurance, and assistance in the interpretation of results, backed by a dedicated customer support team and overseen by the company’s full time geneticist.

You might want to stay away from DNA tests if you or any of your close relatives have committed a crime. Although ancestry DNA testing companies don’t typically share database information with law enforcement, consumer DNA tests may result in future identification. For example, FamilyTreeDNA, which has a database of close to a million samples, has agreed to give the FBI limited access to the company's DNA database. This access consists mainly of consumer-level insights, like matches with other members of the FamilyTreeDNA community who have enabled family matching; by law, however, more in-depth investigation requires a subpoena.
Living DNA supports 80 geographical ancestry regions, 21 of which are located within Britain and Ireland alone, making it a great DNA test for people wanting to delve deep into their British heritage. Of course, it also covers 60 regions outside of the British Isles, and is expanding its efforts to bring the same level of detail to other world regions.
The first kit I try is Thriva’s baseline test (£49), which, like all its products, checks your blood. The box arrives promptly enough (containing spring-loaded needles, a little collection tube, antiseptic wipes, plasters, etc), but there’s a problem. The idea is to prick your finger and massage blood into the tube, but I just end up making my fingers sore and what I get out barely smears the top of the phial. Maybe it’s just me, but it turns into a right faff. In the end, I take advantage of Thriva’s service to send someone out to take a sample of blood from my arm.
After collecting spit and cheek cells, we mailed all of the tests at the same time and waited for results, noting all communications from the company in the meantime and how long it took each service to notify us that results were ready to view. We collected data based on testers’ impressions of their results, each service’s features and extras, how easy it was to use and navigate the service’s website, along with several other factors. We added this testing data to rigorous research and information gleaned from conversations with representatives from Ancestry, 23andMe, MyHeritageDNA, LivingDNA, Humancode (now owned by Helix) and 24genetics. 

Finally, if you happen to meet a special someone on DNA Romance and want to see what your future child together might look like, there’s BabyGlimpse by HumanCode. Like a very advanced Punnett square, BabyGlimpse compares your and your partner’s DNA to create a profile that examines which traits your offspring might inherit, including things like ancestral DNA, eye color and lactose intolerance.


What we would expect to find then in this example is that the two descendants of John show a very close match, and the two descendants of James also show a very close match (because we know from conventional paper based research that they are related). If all four match very closely, then that’s further evidence to add to our theory that John and James were really brothers. Not conclusive proof- but pretty solid evidence.
the beauty of a y-DNA test is that it tracks the paternal y-chromosome…..yes, even indicating a surname change but not when the surname changed [does not match known male descendants]. In all DNA testing, it really helps to have researched about 5 generations back on all lineages……that way you can find common surnames in the autosomal tests. The y-DNA tests go back for centuries…..and the autosomal testing really only goes back about 5 generations…….

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.
The DNA holds or stores the information using code in various forms, configurations, instructing cells what to do. Yes the DNA sends out instructions, ( or "tells" other celss what to do etc.. like a computer program can tell a robot what to do or carry out multiple functions. My question still remaining is... information came from an intelligent mind... not the physical data that it holds like DNA holds the information, it can copy the information.. but DNA did not code itself...it received the instructions.. no matter how long ago from a mind or an intelligent designer. Does ANYONE on this site agree? I have not seen anyone else question this.
GEDmatch is a service where anyone with raw DNA data can upload it, see a list of cousin matches and use a powerful selection of advanced tools to analyze their data. The service is free and powered by donations (extra tools are provided to those that donate). From parental phasing and triangulation, to a variety of admixture calculators and a robust database of people from all testing companies, GEDmatch is the best place to go to explore your genetic data in detail. The system accepts raw data from any one of the main testing companies and has a proven track record of properly managing user information.
Familial hypercholesterolemia (FH) is a genetic condition associated with very high levels of cholesterol in the blood, specifically low-density lipoprotein (LDL), or "bad" cholesterol. High cholesterol due to FH increases the risk for early cardiovascular disease, which can lead to a heart attack. This test includes 24 genetic variants linked to FH.
Every human carries two copies of the genetic code, one inherited from the mother and one from the father, some 6 billion letters in all. Apart from identical twins, no two individuals have the same genetic code.  With the exception of the egg and sperm cells, all the cells of our bodies have 23 pairs of chromosomes, 46 in all. One chromosome of the pair is inherited from the father and one from the mother. However, in males the 23rd pair consists of a so-called Y-chromosome and an X-chromosome, whereas females have two X-chromosomes.  The Y chromosome contains a gene which triggers embryonic development as a male and carries information about the male’s paternal lineage.
