Abstract

The impact of pedigree information and SNP location determined from either the UMD3.1 genome sequence assembly or the USDA-AIPL map on phasing accuracy were evaluated for 2 chromosomes in 2,778 parent verified Angus sire/offspring pairs. DAGPHASE (Druet and Georges, 2010), using a single generation pedigree was superior to BEAGLE software (Browning and Browning, 2007) for phasing. Results based on USDA-AIPL map are closer to expectation than those based on UMD3.1, but the difference is not significant. Recombination hotspots weredetected near 4 and 82Mb on BTA14, and near 25Mb on BTA15.
