Investigative Genetic Genealogy Concepts

Investigative genetic genealogy involves using DNA from crime scenes or unidentified individuals to find relatives through genetic databases. This process helps build family trees to identify potential suspects or unknown individuals. Originating from family history and Y chromosome testing, it has evolved to include comprehensive genetic testing. However, challenges such as lack of regulation and high costs persist, limiting its use in some countries.

What is the primary purpose of investigative genetic genealogy?

• To study ancient DNA

• To modify genetic traits

• To identify relatives of unidentified individuals or perpetrators

• To create new DNA sequences

How does DNA typing help in investigative genetic genealogy?
