MOLECULAR MARKERS FOR IDENTIFICATION OF FAT AND LEAN PHENOTYPES IN CHICKENS

摘要

The invention provides molecular methods of screening chickens to determine those more likely to have a lean or fat phenotype by identifying the presence of at least one polymorphism in genetic material of a chicken in the thyroid hormone repressible gene (THRG) or its 3' untranslated region (SEQ ID NO: 1) that is associated with a fat phenotype or a lean phenotype. The invention also provides methods of screening chickens to identify a polymorphism associated with a fat or lean phenotype. The invention further provides oligonucleotide probes and primers useful for detecting the polymorphisms associated with a fat or lean phenotype.
