They are as follows: 1. mean probability of exclusion (PE) which characterizes the informative value of the experts opinions and is the same in all the disputes evaluated by this expert. 2. relative frequency of men chosen at random from the population and excluded at given phenotype of mother and child (RME). 3. probability of paternity (PP) for particular trio: mother-child-the accused man.
