There are numerous applications for DNA testing. Some people use them to make interesting discoveries about their ancestry, while others undergo testing to determine parentage or prove familial relationships for legal purposes. Regardless of the application, there are three types of tests used to determine crucial genetic information. This guide explains the key differences between them. 

What Are the Common DNA Tests & How Do They Work?

1. Y-DNA

Y-DNA tests can only trace male lineage throughout families. This is because the Y chromosome is only found in biological males, who have an X-Y combination. On the other hand, biological females have an X-X combination. Y chromosomes typically do not change much as they are passed down throughout generations. As a result, it may be possible to trace a person's male lineage back thousands of years. However, because female ancestors are excluded from the search, the results are somewhat limited. 

2. Autosomal

Autosomal testing looks at a person's autosomes, which are the 22 pairs of chromosomes you receive from each parent. This provides information about all ancestors, both male and female, which paints a more comprehensive picture of lineage. Besides helping people locate recent relatives, autosomal tests can also provide information on distant ancestors, such as where they lived and their ethnicity. 

3. Mitochondrial

Often referred to as the powerhouse of the cell, mitochondria are passed down via mothers' eggs. Accordingly, mitochondrial testing traces this genetic material, letting you determine your maternal lineage. Like Y-DNA testing, results are limited because they only focus on female family members. Unlike Y-DNA tests, both men and women can undergo mitochondrial testing because both contain mitochondria from their mothers.
