Genetic relationships between Swiss sheep breeds were estimated on the basis of microsatellite analysis. In addition to the Swiss breeds wild‐type Mouflon was included in this investigation. Polymerase chain reaction amplifications of 31 ovine, bovine and caprine microsatellites were performed in a total of 307 animals representing eight populations. The average heterozygosity within each population was high in the domestic breeds (0.60–0.71) and lower in Mouflon 0.45. The average coefficient of gene differentiation G ST over all loci was 0.17, i.e. a small part of the variability at the 31 microsatellite loci analysed must be ascribed to between‐breed variability. Genetic distances between breeds were obtained, which were used to construct a phylogenetic tree. Microsatellites developed from closely related species of cattle and goat are useful for estimating genetic relationships among sheep breeds.
