摘要

Method of identifying animals or bovine carcasses, polinucleotu00ecdeo isolated, PCR product, pair of PCR primers, and kits for identifying animals or bovine carcasses. Provides methods and compositions to identify objectively if: (I) bovine animals having genetic potential to produce meat that is marmorizada or smooth.And (II) bovine carcasses whose meat is marmorizada or soft.The methods comprise extracting DNA from a sample obtained from a bovine animal or carcass, to test for the presence of a DNA comprising a sequ00b3u00eancia, referred to hereinafter as "marker gene".In the DNA sample. In one aspect, the genetic marker is a marker of mottling, and understand the sequ00b3u00eancia shown in SEQ ID No. 1.In another aspect, the genetic marker is a marker of softness, and understand the sequ00b3u00eancia shown in SEQ ID No. 2, SEQ ID No. 3, SEQ ID No. 4 or combinations thereof.The compositions include primers that amplify markers of meat marmorizada or soft flesh present in genomes of bovine animal or carcass.And hybridization probes to detect markers of mottling or softness.
