Take ancestry testing for example.

When a tube of spit or a cheek swab arrives at the lab, they have to extract your DNA first. They then amplify your DNA (copy it many times over) to prepare it for analysis.

Interesting Facts About DNA

Your Ancestry DNA Test Results Do not Determine Your Identity

Why did you get a genetic DNA test? Or if you are planning to get one soon, why are you doing it?

Understanding degrees of cousins in your DNA Matches on Ancestry

Understanding Degrees of Cousin-ness: 1st Cousin, 2nd Cousin and Beyond

The majority of DNA matches on Ancestry, 23andMe or FTDNA will be your cousins.

Now and then you might stumble on a half sibling or parent but cousins will make up most of the matches on your list.

They are – obviously – not at the same level of relatedness. Some are closer than others.

The closest are first cousins. The furtherst are fourth or fifth cousins depending on how far back the DNA testing company goes.

What do all these levels/grades mean? And what about terms like first cousin once removed?

This quick explainer has all the answers.

Paternal and Maternal lineages ftdna Autosomal DNA test

How to Tell if a DNA Match is Maternal or Paternal (for Autosomal DNA Tests)

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 >>

Why Does Health and Ancestry DNA Testing Take So Long?
