The glucose phosphate isomerase GPI locus is closely linked to the halothane sensitivity locus in pig. The chromosomal localization of GPI in pig was confirmed to 6p12→q21 by using in situ hybridization. Of the total grains, 25 percent were located on chromosome 6, with about 65 percent clustered in the cent→q21 segment, suggesting the presence of the GPI gene on the very proximal part of the q arm. The efficiency of hybridization was found to be affected by ultraviolet irradiation of metaphases for RBA‐banding before hybridization. The irradiated metaphases had higher background grains than the non‐irradiated metaphases.
