Paternity exclusion in primates: Two strategies

Two strategies for the use of polymorphic biochemical and serological markers in paternity testing problems in non‐human primate groups, where pedigree information is incomplete, are discussed. The positive approach, of attempting to prove paternity, is shown to be impracticable given the levels of detectable genetic variation among primates. The more conventional approach of paternity exclusion is examined and found to be useful under certain conditions. This approach is illustrated using the published data on the levels of biochemical and serological variation in Macaca nemestrina.
