In this edition of Naked Genetics from University of Cambridge listen to Professor Mark Jobling discuss how academic DNA sequencing intersects with genealogy research. While he understands that people want to know where their ancestors come from, the reality is that our ancestors didn't come from one specific location - they came from everywhere. The only ancestors we can trace with any confidence are those that passed down their Y chromosome and their mtDNA which represent only two individuals. This segment opens the program.
Then unless you are super keen on genetics, skip ahead to 18:07 to hear Dr. Turi King discuss her research on the Y-chromosome. She uses this chromosome in connection with surnames to trace Norse Viking migrations.
