Abstract: The invention concerns the use of a genomic marker comprising a nucleotide sequence corresponding to all or part of the nucleotide sequence SEQ ID No 1, or to all or a part of an allele of the nucleotide sequence SEQ ID No 1 and associated with the phenotype relating to the tenderness of the meat from bovines, for the implementation of any identification method for the quantification of DNAJA1 expression level with the aim of selecting and/or sorting ruminant animals of the bovine type which produce tender meat and/or for the implementation of an identification method of tender meats at the moment of slaughter by direct sampling from the carcass. The invention concerns identification methods using the real time RT-PCR technique, the hybridization of labelling cDNA with an oligonucleotide probe and the detection of antigen-antibody complexes.
