What’s The Difference? Y-DNA vs. mtDNA vs. Autosomal DNA Explained (+ Tips for Choosing the Right One)

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:

  1. paternal DNA (Y-DNA)
  2. maternal DNA (mtDNA) and,
  3. autosomal DNA (atDNA)

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 >>

Online genetic testing takes 6-8 weeks

Why Does Health and Ancestry DNA Testing Take So Long?

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.

For instance, FTDNA’s 500-marker Big Y ancestry test currently has a turnaround time of 10-12 weeks. That’s … Read the rest >>

23andme Neanderthal DNA report will tell you if you have ancient DNA

What the Heck is Neanderthal DNA and What Does it Mean If You Have Some?

Feature image credit: Erich Ferdinand, Flickr.

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 hard to say that this or that is the most accurate DNA test

Is Genetic DNA Testing Always Accurate? (Short Answer: No)

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 >>

Dog DNA tests reveal dogs to be much closer to wolves than originally thought

How Much Of Your Dog’s DNA is Wolf? (Hint: Almost All of It)

Your dog is 99.9% wolf.

That might be hard to believe considering the gentle mannerisms and cute looks of some breeds. But most of the dog breeds you see today are as a result of artificial selection by humans.

The first German Shepherd for instance, dates back to one dog that lived just over 100 years ago in Germany.

But all dogs share a genetic history that goes back tens of thousands of years; all the way back to a now-extinct wolf species from which researchers theorize all dogs descended from.

Today, despite having tens of thousands of years to … Read the rest >>

How to Use DNA Testing services like AncestryDNA to find your birth family

A DNA Testing Guide for Adoptees: Tips & Resources to Find Your Birth Family

DNA testing through services like AncestryDNA and FTDNA is incredibly helpful for adoptees trying to track down their biological parents.

Years ago the best way for adoptees to find their biological family members was using adoption and family records which can be hard to access and don’t always help.

Reunion registries like reunionregistry.org, and the International Soundex Reunion Registry are helpful but they depend a lot on luck. Both parties must be actively seeking each other for the best chances of success.

The rise of consumer DNA testing has provided another much more effective tool for adoptees to track … Read the rest >>
