Compare and contrast the terms Paternity Index (PI) and Combined Paternity Index (CPI). How does each contribute to paternity determination?

Question

Accepted Answer

Hello, welcome back. Here's the next problem. It is a statistical calculation that measures that the likelihood that a man is the biological father of a child based on the DNA profiles of the child, the mother and the alleged father. Now, the only little tricky thing here is that we have both paternal lineage index and paternity index. But we're specifically talking about the likelihood that a man is the father of a child. So that would be choice C paternity index, paternal lineage index would be the likelihood that two individuals share a common paternal ancestor. And that would be done with things like Y chromosome analysis, but it is not what we are looking for. So we'll eliminate that then choice B discrimination index is the ability of a statistical analysis to distinguish between two groups, but not what we're looking for here. So we'll cross out choice B and finally to the A match index. And that is a probability that a DNA sample matches a suspect's DNA or DNA from a database, but again, not what we're looking for. So not our correct answer. So again, the statistical calculation that measures the likelihood that A particular man is the biological father of a particular child. Is Choice C A paternity index. See you in the next video.
