PATER: a program for parenthood diagnosis.

Spectacular progress has been made within the last 20 years in the knowledge of the human polymorphism. These data, observed on a father-mother-child triplet provides aid to the decision for the parenthood diagnosis for either the purpose of forensic medicine as the validation of data files in genetic research. This work gives an algorithm of parenthood diagnosis which achieve logical verifications and various calculating while occupying very little place in central memory. We propose a tool for decision-making, the exclusion percentage and we determine the most efficient sequence having the least cost to use these systems sequentially and to stop the verification by a given decision threshold.
