Seventy-seven cases of disputed parentage were studied using the human leucocyte antigen system over a 14-year period in Hong Kong. Of these, 30 (39.0%) related to the amendment or verification of birth registration details, 20 (26.0%) were for divorce or affiliation proceedings, and 19 (24.7%) were related to overseas resident visa applications. An exclusion of parentage of at least one of the...

For identification of individuals and parentage control performed by cattle breeders in the Czech Republic, a novel Finnish Bovine Genotypes™ Panel 3.1was amplified by means of one multiplex polymerase chain reaction. Bovine Panel encompasses all the 12 STR loci recommended by the International Society for Animal Genetics (ISAG) for routine use in parentage testing and identification, including...

This study was performed for parentage verification of the Korean native horse (KNH). 103 random KNH samples (including 19 foals for parentage testing) were genotyped by using 16 microsatellite markers. The number of alleles per locus varied from 5 to 13 with an average value of 8.56 in the KNH. The observed heterozygosity and the expected heterozygosity ranged 0.3980.893 (the average value was...

The present study was undertaken to construct a multiplex microsatellite panel for parentage testing in Mehsana buffalo (Bubalus bubalis). The study was based on a total of 212 Mehsana buffalos (100 dams, 100 daughters, and 12 sires). Genomic DNA was extracted from blood and semen samples. A panel of 10 microsatellite markers (CSSM61, ILSTS29, ILSTS17, ILSTS28, CSSM57, CSSM22, ILSTS61, CSSM8, E...

Estimation of short tandem repeat (STR) multilocus genotype frequencies for the identification of individuals and estimation of allele frequencies for parentage assignment both depend on (a) testing a lot of loci, (b) high levels of polymorphism at each locus tested, and (c) independence among alleles. Independence is critical, because the estimation of multilocus genotype and gamete frequencie...

The formulae for computing the so-called Sib Index using codominant alleles for (1) full-sib and (2) half-sib parentage are given. Hypothesis testing is based on the distribution of conditional likelihood ratio or Bayes' factor. Thresholds for rejecting the null hypothesis and P-values were obtained in function of the number of alleles and their frequency distributions. Simulations showed that ...

In this study, microsatellite markers, developed for Alligator mississipiensis and Caiman latirostris, were used to assess parentage among individuals from the captive colony of Caiman latirostris at the University of São Paulo, in Piracicaba, São Paulo, Brazil. Many of the females in the colony were full siblings, which made maternal identification difficult due to genotypic similarity. Even s...
