A report of the 2002-2008 paternity testing workshops of the English speaking working group of the International Society for Forensic Genetics.

The English Speaking Working Group (ESWG) of the International Society for Forensic Genetics (ISFG) offers an annual Paternity Testing Workshop open to all members of the group. Blood samples, a questionnaire and a paper challenge are sent to the participants. Here, we present the results of the 2002-2008 Paternity Testing Workshops with the objective to evaluate the uniformity of DNA-profiling and conclusions of the participating laboratories as well as to clarify tendencies in typing strategies and biostatistical evaluations of the laboratories.

Hybridization between subspecies of waterbuck (Kobus ellipsiprymnus) in zones of overlap with limited introgression.

Two subspecies of waterbuck (Kobus ellipsiprymnus), common (Kobus ellipsiprymnus ellipsiprymnus) and defassa (Kobus ellipsiprymnus defassa), are recognized based on differences in rump pattern, coat colour and geographical distribution. These forms are parapatrically distributed with an area of range overlap in East Africa, where phenotypically intermediate populations occur. Variation in 478 bp of the mitochondrial DNA control region and 14 polymorphic microsatellite loci were used to describe the genetic structure and phylogeographical pattern of the species, and to assess if the intermediate populations are the results of hybridization.
