RLP 228: The Effect of Pedigree Collapse on DNA Matching: A Case Study

Today's episode of Research Like a Pro is about pedigree collapse and its effect on DNA matching. We discuss the coefficient of relationship calculation and how that can help you estimate the expected amount of DNA two people should share based on the relationship in their trees. We talk about the Hopper case study with a DNA match with two individuals with multiple relationships and one of the test takers has pedigree collapse on the relevant line.
