It could be that, in the main, genetic-testing kits such as these could, if promoted and used responsibly, end up zoned completely away from legitimate science and medicine and placed where perhaps they belong, firmly in the lifestyle-extra zone, if and when people think they’re “worth it”. Though, somewhat tellingly, when I ask Newman if he thinks that any of the genetic testing kits are worth buying, he instantly says: “No. I’d say, go to the cinema, watch some sport. Spend the money on something nice, something life-enhancing.”
As stated at the start of this guide, each one of the main tests will provide you with easy-to-use reports and cousin matching that you can use in your genealogy research. You will need to carefully review the information provided in this guide to make a decision about which test is best for your particular needs. You may also choose to test with (or upload your results to) multiple companies.
Is this a perfect method? No, but it’s a good way to get a general idea about where your ancestors were from. Genealogical DNA tests can tell you a lot about your ancestry going back 300-500 years in time, for the most part. They can also tell you a little bit about your ancestry going even further back. This is why comparing your DNA to those whose families have stayed in a particular area for a long time is a fairly accurate way to perform the estimate.
A. Be aware of DNA tests advertised at this price. DNA Clinics have received calls from many anxious individuals who have had these DNA tests carried out for £59 only to realise that the test has been performed at an overseas non UK accredited laboratory. DNA Clinics most affordable test is a Peace of Mind Paternity DNA test available for £119 from www.homednapaternitytest.co.uk. Whilst this is more expensive than the £59 DNA test, you have the reassurance that all testing has been performed at Crystal Health ISO17025 accredited laboratory using strict chain of custody protocols.
Men have an X and a Y (chromosome) that are paired together. Women don’t have the Y, they just have two X’s. A child’s genes come from a mix up and recombining of the two parents. So a girl child will still end up with two X’s but some bits of them will come from the father’s X and some from the mother’s. A boy child on the other hand may have some bits of X from both mother and father, but his Y will have just come purely from his father – virtually unchanged. That makes Y-DNA such an exciting possibility for genealogy where you want to follow the paternal (surname) line. You could expect that Y-DNA will therefore pass virtually unchanged from father to son through the generations, meaning that the Y-DNA of a man’s g-g-g-g-grandfather will look very much like that of his own Y-DNA – with some little changes.
Most companies will use algorithms to compare the genetic variants uniquely associated to a reference population with those identified in the person being tested. This can help them exclude unlikely population groups from your ethnic mix, and ensure that the ethnic groups you’re shown to be composed of are more accurately reported. Although most companies will share the reference populations they use with their customers, they rarely provide information on the algorithms they’ve developed.
Family Tree DNA (the longest running testing company) offers a well-established database of “cousins” and advanced tools for exploring your results. MyHeritage offers the ability to sync your results with your family tree research in a very unique way. Both are a good choice, but since every person’s needs are unique we suggest you read the full guide before deciding.
The test kit gathers saliva from spit. It offers a free family tree tool to which users can contribute their specific results. You can also download your full DNA profile and import that data into another tool -- but it doesn't offer a chromosome browser, so you can't really do DNA segment comparisons. Given this, if you're a true DNA geek, Ancestry may not be the service for you.
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.
While 23andMe does offer DNA relative matching and some tools to compare your genes to your DNA relatives, it doesn’t have robust genealogy tools, as its focus rests more in personal discovery and exploration. To that end, 23andMe has an optional health upgrade that provides reports on DNA traits like hair color and genetic predispositions to certain illnesses and diseases. It is the only DNA test with FDA approval for testing genes linked to conditions such as Type 2 diabetes, certain types of cancer, late-onset Alzheimer’s disease and Parkinson’s disease. If you’re interested in the health portion of the test, we recommend buying the Health + Ancestry test together, as this option costs less than upgrading later.
1. Family Tree DNA’s Family Finder: One of the first to offer these types of tests, FTDNA is generally considered the leader in autosomal DNA testing for ancestry and provides some of the best tools available for genealogists. Their population finder section is currently a bit less specific than the other companies, but FTDNA Family Finder users are eagerly awaiting a much improved update to be released sometime in the next month.
