ABSTRACT
The chromosomal location of the porcine gene for glucose phosphate isomerase (GPI) was previously mapped to 6p 12----6q21 in the pig karyotype. The replication patterns and morphology of this chromosome are very similar to those of chromosome 14 in the rabbit karyotype. With combined in situ hybridization and RBG-band induction it was demonstrated that the porcine GPI-probe hybridized most frequently to 14p11----14q12 in the rabbit karyotype, indicating a close relationship between morphology, replication pattern and gene location.

Nucleolar organizer regions (NORs) in the female dog karyotype are presented. Eight autosomes Nos. 5, 8, 14, 16, 19, 21, 32, and 37 showed active NORs. We observed a high incidence (50%) of metaphases with NOR association.

A method to preserve high resolution R-bands on human lymphocyte chromosomes after in situ hybridization to 3H-labelled probes and autoradiography is presented. The technique was used to re-examine the location of the known oncogene N-myc. Due to the high resolution power of the present technique, this gene could be located to subband 2p24.1 in the human karyotype.
