| During the last decade, microsatellites (short tandem repeats or STRs) have been successfully used for animal genetic identification, traceability and paternity, although in recent year single nucleotide polymorphisms (SNPs) have been increasingly used for this purpose. An efficient SNP identification system requires a marker set with enough power to identify individuals and their parents. Genetic diagnostics generally include the analysis of related animals. In this work, the degree of information provided by SNPs for a consanguineous herd of cattle was compared with that provided by STRs. Thirty-six closely related Angus cattle were genotyped for 18 STRs and 116 SNPs. Cumulative SNPs exclusion power values (Q) for paternity and sample matching... |

| The use of marker-based pedigrees is increasing in aquaculture breeding, and obtaining high assignment rates is necessary for practical use of this methodology. In this paper, we used 12 real parentage assignment datasets from three species (European sea bass Dicentrarchus labrax, common carp Cyprinus carpio and rainbow trout Oncorhynchus mykiss) to investigate the relationships between theoretical, simulated and real assignment power. We found out that there was a large decrease between the theoretical and the observed values, which we modeled in four independent steps: 1) from theoretical values to population-wise simulations (-2.8% on average), 2) from population-wise simulations to true parent set specific simulations (-2.6% on average), 3) from true... |
