Förekomsten av den genetiska varianten laktapersistens hos neolitiska grupper från Öland : The contribution of the genetic variant Lactase persistence among Neolithic people from the Baltic island Öland in Sweden

This study deals with the contribution of the genetic variant lactase persistence among Neolithic people from the Baltic Island Öland. Skeletal remains from twelve individuals went through DNA sequencing in order to find the mutation that allows adult individuals to digest milk sugar. The twelve individuals were chosen from two different Neolithic sites, where the archaeological and isotopic data suggest that the individuals from Köpingsvik were hunters and gatherers and the individuals from Resmo were early farmers. The individuals with the genetic variant lactase persistence can be described with selection and genetic flow.  Only five individuals produced results and the mutation was found in two of the subjects. All the individuals who were successfully sequenced came from Resmo, whereasno individuals from Köpingsvik yielded any results.

DNA Analysis on a Viking-age boat grave from Sala hytta Västmanland, grave A2

Viking-age boat grave burials are a less common but still repeatedly used way to bury the dead during the late Iron Age. Boat burials are exceptional in many aspects, not only due to placing the individual in a boat with numerous burial gifts including animals, but also by burying the individual without prior cremation, a common practice during the Iron Age. The aim of this thesis is to genetically analyse inhumation boat graves and compare the genetic composition of the ancient individuals with modern populations through population genetic analyses. This will highlight these particular human remains in a mobility context. A total of 11 individuals was analysed, but only one yielded enough DNA for further statistical analyses. This one individual proved genetically exceptionally well preserved. The results clearly show that the individual (a female) has a genetic affinity to populations in northern Europe. However, the results do not discriminate between modern Baltic/Scandinavian populations, depending on the statistical test
