Defining a Haplotype Encompassing the Locus Associated with Increased Lean Growth in Beef Cattle.

Numerous studies have shown genetic variation at the locus is strongly associated with growth traits in beef cattle. However, a causative molecular variant has yet to be identified. To define all possible candidate variants, 34 Charolais-sired calves were whole-genome sequenced, including 17 homozygous for a long-range haplotype associated with increased growth () and 17 homozygous for potential ancestral haplotypes for this region ().
