• Genetic structure and admixture in sheep from terminal breeds in the United States

    18 days ago - By Animal Genetics

    Summary
    Selection for performance in diverse production settings has resulted in variation across sheep breeds worldwide. Although sheep are an important species to the United States, the current genetic relationship among many terminal sire breeds is not well characterized. Suffolk, Hampshire, Shropshire and Oxford and Rambouillet sheep sampled from different flocks were genotyped using the Applied Biosystems Axiom Ovine Genotyping Array , and additional Shropshire sheep using the Illumina Ovine SNP50 BeadChip. Relationships were investigated by calculating observed heterozygosity...
