Living DNA and Findmypast are British companies joining forces to combine cutting-edge science with traditional family history research methods. We’ve made every effort to find a DNA company to partner with that provides the most benefit for those looking to explore their British and Irish roots. Living DNA's test results provide a regional breakdown that perfectly complements our unrivalled collection of British and Irish historical records. It’s this powerful combination that makes this partnership the perfect marriage of science and history.
Then comes the section about serious genetic variants. So far as “counselling” goes, previously, I’d waved away concern for my psychological welfare from the Observer’s science editor (“I’m a former goth,” I said. “My default setting is ‘doomed’”), but it turns out to be quite daunting. It doesn’t help that I initially mistake the full list of potential conditions for my own results, hence (thankfully briefly) thinking that I have higher risk factors for everything going. It makes me wonder – how many other people are going to do that?
Prices range from £100 to £200 for a basic DNA profile, but it’s worth mentioning that the cost largely depends on what you intend to do with it. One of the major factors that you need to consider, and which significantly impacts the cost, is whether you want your DNA profile to be legally admissible or not. Legal DNA profiles cost more than peace of mind versions, but if there’s a chance that your profile will be used in legal proceedings, it’s worth paying extra for.
Alternatively, if you believe your "Italy/Greece" result indicated your known Italian heritage, it is possible that your son simply did not inherit the associated DNA from you. We all inherit roughly half our DNA from each parent, but the DNA we inherit is selected at random, and so even full siblings can have different ancestry results, depending on which genetic variants they inherited.
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. 
Like many of the best DNA test kits, Living DNA examines autosomal and mitochondrial DNA, as well as Y-DNA for males. The service’s Family Networks feature, currently in beta, allows customers to find DNA relatives within its database. I received test results 27 days after dropping my sample in the mail. One fun Living DNA feature is that you can order your DNA analysis in coffee table book form.
The last ancestry-related report from 23andMe is your DNA Family. This report is separate from the relative matching feature, which you have to opt-in to. It tells you very generalized information about the people in the database who share segments of DNA with you, including states of residence, similar geographical ancestral regions and traits like the ability to wiggle your ears or whistle.
The Y chromosome is a special chromosome, passed on from fathers to their sons, while mothers pass on mtDNA to both their sons and daughters. But mtDNA dies with men and so it survives only in the female line. This means that a man’s lineage can be followed along both paternal and maternal lines, while in a woman only her maternal or mtDNA line can be followed.
