Abstract
Genetic markers could provide a tool to estimate inbreeding in absence of known pedigree. In the present work, 62 individuals from two related strains of Iberian pigs (32 from Guadyerbas and 30 from Torbiscal), with a deeply known pedigree, have been genotyped for 49 microsatellite loci. The inbreeding values, calculated from pedigree, have been compared to the molecular inbreeding values or homozygosity, calculated from molecular markers. Simulations were also carried out to facilitate the interpretation of the results. The correlation between genealogical and molecular inbreeding was negative for the Guadyerbas (0.32), low for the Torbiscal (0.19) and substantial for all the animals together (0.69). In conclusion, it seems preferable to use pedigree information whenever available, and limiting the use of markers to verify, correct, complete or even implement pedigree recording.Downloads
