A porcine 17kb genomic fragment was used as probe to map the lactase p
hlorizin hydrolase (LCT) gene to pig chromosome 15q13 by fluorescence
in situ hybridization. Further, a three-allele TaqI RFLP was used to a
dd 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,
