An ABC estimate of pedigree error rate: application in dog, sheep and cattle breeds.

On the basis of correlations between pairwise individual genealogical kinship coefficients and allele sharing distances computed from genotyping data, we propose an approximate Bayesian computation (ABC) approach to assess pedigree file reliability through gene-dropping simulations. We explore the features of the method using simulated data sets and show precision increases with the number of markers. An application is further made with five dog breeds, four sheep breeds and one cattle breed raised in France and displaying various characteristics and population sizes, using microsatellite or SNP markers.

Genetic variability, structure and assignment of Spanish and French pig populations based on a large sampling.

The Spanish and French pig populations share the common practice of quasi systematic paternity control of pure breed and composite line males. Ten microsatellite markers are in common between Spain and France controls, among the 17 markers used in France and the 13 used in Spain. After the adjustment of allele sizes, it is possible to merge the two datasets and to obtain a set of 5791 animals, including the vast majority of the males in the Duroc, Landrace, Large White and Piétrain French and Spanish breeds.

Genetic diversity of a large set of horse breeds raised in France assessed by microsatellite polymorphism.

The genetic diversity and structure of horses raised in France were investigated using 11 microsatellite markers and 1679 animals belonging to 34 breeds. Between-breed differences explained about ten per cent of the total genetic diversity (Fst = 0.099).

Genetic diversity of dog breeds: within-breed diversity comparing genealogical and molecular data.

The genetic diversity of 61 dog breeds raised in France was investigated. Genealogical analyses were performed on the pedigree file of the French kennel club. A total of 1514 dogs were also genotyped using 21 microsatellite markers.

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.
