Genetic diversity and population structure of Swedish sheep breeds was studied using pedigree data and molecular genetic information. Both pedigree information and microsatellite genotypes showed that inbreeding has been successfully managed in the ancient Gute sheep breed, despite it being a small local population. The population structure of five Swedish…

Researchers from Aarhus University’s Center for Quantitative Genetics and Genomics mapped the old livestock breeds’ relationships with each other and with breeds abroad, the structure of breeds and their genomic inbreeding degrees. Results are described in the report ‘Old Danish livestock breeds genomes – the breed origin and kinship’, published…

Although these breeds have probably gone through severe bottlenecks, they still express high phenotypic variation, e.g. in body size and plumage colour. Genetic variation and relatedness of the Swedish local chicken breeds had to date not been investigated. Three molecular genetic studies recently shed light on relationships, population structure and…

A recent study, published in the scientific journal Journal of Animal Science, has genetically characterized a herd of Danish Jutland cattle. The study is based on 135 individuals from the Kortegaard herd of Danish Jutland cattle, which has been genotyped with the HD cattle chip, containing more than 700.000 genetic…
