Genetic diversity of dog breeds: between-breed diversity, breed assignation and conservation approaches.
Genetic relationships between 61 dog breeds were investigated, using a sampling of 1514 animals and a panel of 21 microsatellite markers. Based on the results from distance-based and Bayesian methods, breed constituted the main genetic structure, while groups including genetically close breeds showed a very weak structure. Depending on the method used, between 85.7% and 98.3% of dogs could be assigned to their breed, with large variations according to the breed. However, breed heterozygosity influenced assignment results differently according to the method used. Within-breed and between-breed diversity variations when breeds were removed were highly negatively correlated (r = -0.963, P < 0.0001), because of the genetic structure of the breed set.
