A Y-DNA test is great for researching your paternal lineage and finding matches on your father’s side of the family.
An mtDNA test is great for researching your maternal lineage and finding matches on your mother’s side of the family.
An autosomal DNA test is great for researching your ancestry and finding family matches. Unfortunately, unlike the other two tests, it cannot tell which side of your family those matches are from.
The results of a 23andMe, AncestryDNA or FTDNA autosomal DNA test will simply show a list of matches without specifying whether they are maternal or paternal.
This is … Read the rest >>
Wondering which Family Tree DNA Y-DNA test to order?
In this quick post, we’ll tell you the differences between the four Family Tree DNA tests and help you choose the right one for you needs.
Quick summary: the 37-marker test is a great starting place. The 67 and 111-marker tests provide more reliable and refined results about your relatedness to a certain match. The Y-500 is for expert genealogists.
When you want to research your father’s family line, a Y-DNA test is the place to start.
Because Y-DNA passes almost unchanged from father to son, you can trace your paternal … Read the rest >>
Once you receive your DNA ancestry results whether it’s from 23andMe, FTDNA or AncestryDNA, one of the most interesting parts of the report is the breakdown of DNA ancestry regions.
You’ll see a colorful labelled chart with percentages showing how your DNA splits into various regions. There’ll also likely be a map with color-coded areas to indicate where your DNA originates from.
This part of the report is called admixture or ancestry composition.
Admixture refers to the genetic combination of previously separate populations which occurs when they interbreed.
Almost everyone today has DNA that is derived from the admixture … Read the rest >>
One of the most important things to check when looking for a good DNA ancestry testing service is the type of DNA they actually test. It makes a huge difference in the type and accuracy of information you can learn from the test.
There are 3 basic types of DNA tested by ancestry DNA tests today:
The right DNA test for you depends on the kind of information you want to glean from your test.
Let’s look at each type of test in a more detail – and the … Read the rest >>
After you mail back your sample, it takes quite some time before you get an email telling you the results are ready.
FTDNA, 23andMe, AncestryDNA and other online genetic testing services all provide an estimate turnaround time of 6-8 weeks.
They are also careful to note that this is just an estimate. Your results could take even longer if the volume of tests goes up or your sample needs to be re-tested.
For certain more complex tests, the turnaround time is usually longer.

Here’s a brief accounting of how modern humans came to bear ancient DNA from the Neanderthals.
We split from chimpanzees 5-7 million years ago.
Then around 2-2.5 million years ago, the first hominins (our earliest ancestors), started appearing in current East Africa.
Homo habilis and Homo erectus were among the first human species intelligent enough to develop tools. The latter was the first to learn how to use fire.
About 1.75 million years ago, Homo erectus started migrating out of Africa to Eurasia seeking more food and favorable climate. Some of the … Read the rest >>
It’s not always that genetic DNA testing gives you all the answers you were seeking. More often than not it leaves you with even more questions than before and results that sometimes seem impossible.
It doesn’t matter which DNA testing service you use. It’s hard to say that this or that is the most accurate DNA test. They all operate within the limits of an imperfect science that is based on estimates.
Your genetic testing results are highly researched estimates based on rigorous testing and decades of research. But they are estimates nonetheless.
So, no, genetic DNA testing is not … Read the rest >>
Taking an online genetic DNA test as a beginner can be both exciting and frustrating at the same time.
Exciting because you get to learn something new about yourself and your heritage. Frustrating because understanding the results is not always easy.
Unless you are a seasoned genetic testing expert or hobbyist, you’ll probably not understand all the technical terms used in the report. This will keep you from getting the most out of it.
So I’ve put together this quick primer to help you understand the most commonly used words and terms in ancestry DNA testing.
You’ll come across them … Read the rest >>
Should I try a Paleo, Mediterranean or ketogenic diet? There is a history of heart disease in my family; should I worry about my salt intake? Why can’t I lose weight?
We all have pressing questions on our health and fitness that we’d give anything to have answered.
But we usually have to settle for vague estimations and sometimes no clear answers at all even from doctors.
Now, several new startups say they can answer these questions by analyzing your DNA.
The premise is simple. Pay for home DNA tests and we will study you gene variants to learn how … Read the rest >>
The 23andMe health test report is packed full of helpful information about your genetic health risks. It also includes a wellness report that tells you how your genes influence your health.
But one of the most interesting parts of the test report is the traits analysis that predicts which traits you might develop or why you have certain traits.
The report can predict traits such as hair color, early hair loss for men, dimples and eye color.
Recently 23andMe added four new traits to their traits analysis for a total of 15.
Here are the four new traits.
