About this webinar

All of us are aware that DNA testing is a formidable tool to address paternity cases. However, when talking about paternity testing, the subjects tested are all alive and willing to provide a DNA sample. The normal procedure involves testing the alleged father, the mother and the child. However, what can be done if in our genealogical research we are presented with a similar instance, but that occurred 100-200 years in the past? What to do if the three candidates are now deceased? Is there a way to use DNA testing to confidently reach a conclusion regarding the suspected paternity? In this webinar, Ugo Perego will explain how to use Y chromosome and autosomal DNA testing as tools to unlock suspected biological relationships.
