Know Which Test You Want

DNA tests can be used for many different reasons, including health issues. When considering an ancestry DNA test, there are three main sorts to think about.

The most common one is known as Autosomal DNA.  This will reveal where your family derives from and is sometimes referred to as a DNA ethnicity test. Any gender can take it and receive similar types of results. It is able to let you know in what part of the world your ancestors were from, going back many hundreds of years.

MtDNA tests look at data from your maternal side and will not be able to provide any information relating to males. It can reveal how closely related you are to an ancestral group and can trace your mother's line back for up to 10,000 years.

Y-DNA is the test used when people want their paternity confirmed. It is based on male chromosomes and can let you know how close you are in relation to people with the same surname.

When you see the differences between each type of test, you can understand why some people take several if they are seriously looking to find out all they can about their ancestry.
