The PiGMaP and USDA porcine linkage maps for chromosomes 2 and 5 have been aligned by typing five USDA microsatellite markers from chromosomes 2 and 4 from chromosome 5 on the PiGMaP reference families. The markers in the two maps can be successfully aligned except for Sw395 on chromosome 2, which is the end-most marker in the USDA map 22 cM remote from the next marker, but which maps to a more central location and in the same position as Sw776 in the PiGMaP families. The mapping of four additional chromosome 5 markers has enabled amalgamation of the two previously separate PiGMaP linkage groups assigned to chromosome 5 and has more than doubled the length of its map. The USDA map of chromosome 5 is considerably shorter than the revised PiGMaP version, particularly between DAGK and Sw1071, where the corresponding lengths are 9 cM versus 33 cM.
通过在PiGMaP参考家系中对来自2号染色体的5个美国农业部微卫星标记以及来自5号染色体的4号染色体上的标记进行分型，已将2号和5号染色体的PiGMaP和美国农业部猪连锁图谱进行了比对。除了2号染色体上的Sw395之外，两个图谱中的标记能够成功比对。Sw395在美国农业部图谱中是最末端的标记，与下一个标记相距22厘摩，但在PiGMaP家系中它定位到更中心的位置，并且与Sw776处于相同位置。另外4个5号染色体标记的定位使得之前分配给5号染色体的两个独立的PiGMaP连锁群得以合并，并且其图谱长度增加了一倍多。美国农业部5号染色体图谱比修订后的PiGMaP版本短得多，特别是在DAGK和Sw1071之间，相应长度分别为9厘摩和33厘摩。
