Investigative Genetic Genealogy (IGG)

Looking for a fresh challenge in the New Year? ICFECI may have just the thing for you.

The Institute offers a number of courses for investigators at any stage of their career, boasting an extensive range of programs in all areas of forensic examination. One of our more recent offerings is the Investigative Genetic Genealogy course, also known as IGG.

DNA is a vital source of evidence in any case, and it’s essential that this evidence is handled appropriately. One of the ways we can use DNA is by identifying who it belongs to and explaining why that material might have been found there. For example, we may expect to find a husband’s hair fibers on his wife’s clothing, however it would be less obvious why her tennis coach’s hair would be there.

If we know the source of the DNA already or have suspects who can provide a sample, usually this allows us to piece together who committed the crime. But sometimes DNA can be found that does not match to any of the victim’s relatives, friends or suspects in the case. This foreign DNA must be investigated as it could lead to the arrest of the perpetrator, but how can authorities match the DNA to a complete stranger?

That’s where Investigative Genetic Genealogy comes in. This allows investigators to access public data, personal genomics DNA databases or private company information to see if they can find a match. Automated algorithms generate potential relative matches by finding shared blocks of DNA, submitted voluntarily by users of these services. The IGG course teaches the forensic application of this genetic data and how to use public databases and traditional genealogical records to analyze crime scene samples.

If you’d like to enroll on this course or find out more, get in touch with ICFECI today. One of our experts is always on hand to provide more information and will gladly help you with your query.

  1. Hello this is kind of of off topic but I was wondering if blogs
    use WYSIWYG editors or if you have to manually
    code with HTML. I’m starting a blog soon but have no coding expertise
    so I wanted to get guidance from someone with experience.

    Any help would be enormously appreciated!
