Abstract

Introduction

In this chapter we discuss the evaluation of the joint and conditional probabilities of obtaining various genotypes for two people who are related and the effect of this relatedness on the interpretation process. Formulae are given for some common relationships. Most of this work has appeared elsewhere, for instance in Evett and Weir.257 Elegant algorithms have been published483–485 that perform these and far more complex analyses. Such probabilities have many uses outside the specific forensic context.
