Genotypes of 25 artificial insemination sires were used to study the extent of linkage disequilibrium (LD) and the correspondence between pedigree and SNP-based estimators of inbreeding in Brazilian Gyr dairy cattle. Overall, 24,020 SNPs had minor allele frequencies (MAF) greater than 5 % and were used to calculate two measures of LD (r2 and D’) for all pairs of markers in each autosome. LD was also used to estimate the effective population size (Ne) at different prior generations. Individual inbreeding coefficients (F) were estimated using either pedigree information (Fped, pedigree traced back up to 9 generations) or marker information. Marker-based estimates of F were derived based on the excess homozygosity (Fhet) in SNP markers and the...
