It has been shown that a major gene, called RN, is responsible for the RTN technological yield, a meat quality porcine trait. Experimental families informative for the segregation of RN gene were constituted from animals belonging to the Laconie composite line. We have previously mapped the RN gene to Chromosome (Chr) 15 (Milan et al. Genet. Sel. Evol. 27, 195-199, 1995). A Chr 15 map was established with 16 markers. The RN gene was found to be located between markers Sw120 and Sw936, at 2 cM from Sw936 (LOD = 38.1). In addition, by localizing Sw936 at 15q21-22 using DISC-PCR, we also located RN on the physical map.
研究表明，一个名为RN的主基因决定了RTN技术产量，这是猪的一个肉质性状。利用拉科尼复合品系的动物构建了对RN基因分离具有信息性的实验家系。我们之前已将RN基因定位到15号染色体（Chr）上（米兰等人，《遗传、选择与进化》27卷，第195 - 199页，1995年）。构建了一个包含16个标记的15号染色体图谱。发现RN基因位于标记Sw120和Sw936之间，距离Sw936为2厘摩（LOD = 38.1）。此外，通过使用DISC - PCR将Sw936定位到15q21 - 22，我们也在物理图谱上定位了RN基因。
