Assessing effective population size, coancestry and inbreeding effects on litter size using the pedigree and SNP data in closed lines of the Iberian pig breed.

Abstract excerpt

The complete pedigree of two closed Iberian pig lines (Gamito and Torbiscal), with 798 and 4077 reproducers, has been used to measure the evolution of coancestry (f) and inbreeding (F) for autosomal and X-linked genes along 16 and 28 respective equivalent discrete generations. At the last generation, the mean values of each line were f = 0.41 and 0.22, F = 0.35 and 0.18, fX  = 0.46 and 0.22 and FX  = 0.47 and...
