A porcine 17kb genomic fragment was used as probe to map the lactase phlorizin hydrolase (LCT) gene to pig chromosome 15q13 by fluorescence in situ hybridization. Further, a three-allele TaqI RFLP was used to add the LCT gene to the proximal end of the chromosome 15 linkage map. Comparison of the human chromosome 2 gene map and the gene map of pig chromosome 15 indicates that the part of human chromosome 2 distal to the q13 band is homologous to pig chromosome 15.
使用一个猪的17kb基因组片段作为探针，通过荧光原位杂交将乳糖酶-根皮苷水解酶（LCT）基因定位到猪的15号染色体q13区域。此外，利用一个三等位基因的TaqI限制性片段长度多态性（RFLP）将LCT基因添加到15号染色体连锁图谱的近端。比较人类2号染色体基因图谱和猪15号染色体基因图谱表明，人类2号染色体q13带远端的部分与猪15号染色体同源。
