Mapping of the silver fox genome. III. Determination of the chromosomal localization of the GOT2, AK1, ALDOC, ACP1, ITPA, PGP and BLVR genes

Evidence is presented for the chromosome localization of seven silver fox genes obtained with the help of panel of fox x Chinese hamster somatic cell hybrids. Thus, the AK1, GOT2 and ALDOC are assigned to chromosome VFU2, PGP to chromosome VFU3, BLVR to chromosome VFU5, ACP1 to chromosome VFU8 and ITPA to chromosome VFU14. The genetic map of 29 fox genes is compared with those reported for man and other animals. The results obtained support and extend our previous suggestion that formation of the Canidae branch of the Carnivora phylogenetic tree was associated with great increase in the rate of reorganization of the ancestral karyotype.
