| Popis: | We have constructed a 12,000-rad porcine whole-genome radiation hybrid panel to complement the first generation 7,000-rad panel (IMpRH) and allow higher resolution mapping studies both in specific areas of interest and on the whole genome. We analyzed 243 hybrid clones on the basis of their marker retention frequency to produce a final panel of 90 hybrid clones with an average retention frequency of 35.4%. The resolution of this 12,000-rad panel (IMNpRH2) was compared to the resolution of the 7,000-rad panel (IMpRH) by constructing framework maps in the 2.4-Mb region of porcine chromosome 15 containing the acid meat RN gene. In this region, two-point analysis was used to estimate RH distances and demonstrates their reliability with the estimation of physical distances. This study demonstrates that the 12,000-rad panel constitutes a powerful tool for constructing high-resolution maps. Indeed, the resolution of IMNpRH2 (12–14 kb/cR12,000) is two to three times more than that of IMpRH (35–37 kb/cR7,000). As expected, the increase in the radiation dose allows an increase of the mapping resolution in terms of kb/cR with the same suppleness of use for mapping experiments. In addition the RH map constructed in the region investigated proved to be more homogeneous on IMNpRH2 than on IMpRH. |
