Considering FCGR2 and FCGR3 as a single locus, a three-point linkage analysis for [FCGR2/FCGR3], FCGR1, and INRA003 was carried out.     ///    "Map distances in a two-point linkage analysis were 10.3 cM between [FCGR2/FCGR3] and FCGR1, and 25.5 cM between FCGR1 and INRA003, respectively. "    ///    The best-supported order of the loci was found to be INRA003-FCGR1-[FCGR2/FCGR3].
