*Allelic frequencies in the general Croatian population (data from the Department of Pathology, Forensic Medicine and Cytology, Split University Hospital, Split, Croatia).
†Paternity index was calculated after ref. 18. Using the known allelic frequencies of the general Croatian population, the probability of parentage for this case was calculated to be 38.52%.
