Table 1: Results of genotyping of saliva samples taken 1 minute after intense kissing with AmpFlSTR® Identifiler® Plus PCR Amplification Kit. The results are presented as Y/X Amelogenin ratio and CIOA/CPIOA ratio, which correspond to the male/female ratio and minor contributor allele detection ratio, respectively. * count of identified obligatory alleles; †count of potentially identifiable obligatory alleles.
