Background Brazil stands on the international scenario by having one of the largest natural forest heritage and extensive sustainable planted forests. Brazilian planted forestry is based mainly on fast growing eucalyptus and pines, with the pulp, paper and steel industries as the major consumers. Introduced commercially in Brazil in the early twentieth century, the eucalypts have experienced in...

We investigated the genealogy of the in situ conservation nucleus of the Pantaneiro horse using DNA microsatellites by evaluating 101 horses, the group consisting of 71 adult horses (3 stallions, 40 male and 31 mares) and 27 foals (14 colts and 13 fillies). Genomic DNA was extracted from hair roots and genotyped using 12 microsatellite markers (AHT4, AHT5, ASB2, ASB17, ASB23, HMS3 HMS6, HMS7, H...

OBJECTIVES This preliminary study was carried out to determine the allele frequencies and forensic efficiency parameters for the short tandem repeat loci CSF1PO, TPOX, THO1, D16S539, D7S820, D13S317, vWA, FESFPS and F13B in a test sample population of Sri Lankans. DESIGN Test samples were obtained from 305 non-related individuals originating from all 9 provinces of Sri Lanka. DNA was extracte...

although passing the method of embryo donation to sterile spouses act in 2003 was a positive step toward regularizing one of assisted reproduction methods, but it may be criticized due to some vagueness in its content, lack of sanction, and referring many essential issues to bylaw.  one of the most important problems of this act is that it does not clarity parentage and the legal effects of emb...

AIM To investigate the potential of false inclusion of a close genetic relative in paternity testing by using computer generated families. METHODS 10000 computer-simulated families over three generations were generated based on genotypes using 15 short tandem repeat loci. These data were used in assessing the probability of inclusion or exclusion of paternity when the father is actually a sib...

Short tandem repeats (STRs) are used routinely for the analysis of DNA samples from evidentiary items, convicted offenders, relationship testing and other identity testing disciplines. The discriminatory power of the STRs is sufficient in most human identity testing comparisons to render an identification. However, STRs have some limitations in evaluations, such as parentage testing, identifica...

Parentage analysis and individual identification are recent, promising methods that have been applied to evolutionary and ecological studies, as well as conservation management. Parental exclusion relying on polymorphic microsatellites has been used worldwide in parentage determination, while the low mutation rate and genotyping error rate of single nucleotide polymorphisms (SNPs) make them ano...
