Y-Chromosome DNA Testing is considered a great option to find out a man’s patrilineal or direct father’s-line ancestry. Remember that because women do not have a Y-chromosome, this testing is only performed on men. The Y-chromosome is passed virtually unchanged. If your results are perfectly or near-perfectly matched with a particular ancestral database, then you will be related within a genealogical time frame.

The two matched persons can find a common ancestor or MRCA. In fact, Y-DNA tests are typically coordinated in a surname DNA project; each can receive the other individual’s contact information if he chooses to allow this. Now, it will be easier to know whether two families with the same last name are related or not. Moreover, you can gather information regarding your specific ethnic or geographic origin. For example, if your patrilineal line had European roots, the Y-chromosome will be identical or nearly identical throughout dozens of generations, which will help you in finding your ancestral European roots. All direct male descendants share the same Y-DNA, regardless of how long ago they lived

Two different types of Y-DNA testing

• Short Tandem Repeat (STR)
• Single Nucleotide Polymorphism (SNP)

Y-DNA STR Testing

STR markers are short regions located along the Y-chromosome, and this testing looks at these markers to find sequences of DNA units that repeat a variable number of times. These unique sequences are passed down through generations and determine a genetic relationship between two test-takers.

Y-DNA SNP Testing

Single Nucleotide Polymorphisms (SNPs) are variations in a single unit of DNA, rather than a region, which means this testing digs much further into the details of Y-DNA.
