title: [Diagnosis of paternity by deduction of the probable genotype of the deceased person from the relatives--in addition to the examination of the Essen-Möller value and diagnosis of paternity based on the probability distribution of log (Y/X)].
abstract: 1) The present paper deals with the general formulas of paternity probability, applicable to any cases where the putative man and/or the plaintive mother are deceased, using the blood types of various relatives. Two typical examples are described. 2) Bayes's theorem is applied to the calculation of probability of paternity using the Essen-Möller's formula, in which a putative father is to be compared with any one of the men in the general population whose blood types are unidentified. Statistically, those men are supposed to have any one of several blood types, depending on the frequency of occurrence of those types. This means that their blood types include the blood type of the putative father. According to Bayes's theorem, however, probability calculations are valid only when the two types to be compared are mutually exclusive. Consequently, the theorem should not be applied to probability calculations using the Essen-Möller's formula. 3) A new basis of judgement for the diagnosis of paternity is proposed using the probability distribution of the relative frequencies of log (Y/X) for true father and that for non-father.
