statistical genetics Genotypes determined for a case, e.g. a paternity case father, mother, child can be handed over to the statistical genetics programme. Statistical formulas can be easily programmed for the problem to be solved. Routines to calculate paternity indexes (PI) for father/mother/child or father/child are ready to use. Likelihood ratios for any possible case can be calculated. Two different sets of multiplex kits for one sample can be compared automatically to detect e.g. sample contamination, sample mix up or primer site mutations or other features.
