Methods and compositions are provided for objectively identifying: i) bovine animals having the genetic potential to produce beef that is marbled or tender, and ii) bovine carcasses whose beef is marbled or tender. The methods comprise extracting DNA from a sample obtained from a bovine animal or carcass, assaying for the presence of a DNA comprising a sequence, referred to hereinafter as a "genetic marker", in the DNA sample. In one aspecet, the genetic marker is a marker of marbling, and comprises the sequence set forth in SEQ ID NO. 1. In another aspect, the genetic marker is a marker of tenderness, and comprises the sequence set forth in SEQ ID NO. 2, SEQ ID NO. 3, SEQ ID NO. 4 or combinations thereof. The compositions include primers that ammplify markers of marbled or tender beef present in bovine animal or carcass genomes and hybridization probes to detect marbling or tenderness markers. |
