Molecular probes for the oncogenes of Rous sarcoma virus (v-src), avian myeloblastosis virus (v-myb), Kirsten murine sarcoma virus (v-Ki-ras), and Harvey murine sarcoma virus (v-Ha-ras) were hybridized to the DNA from mouse-Chinese hamster somatic cell hybrids. The v-src, v-myb, v-Ki-ras, and v-Ha-ras genes each detected one or a few homologous mouse DNA fragments whose segregation was analyzed in cell hybrids. Mouse cellular homologs c-src, c-Ki-ras, c-Ha-ras, and c-myb segregated concordantly with chromosomes 2, 6, 7, and 10, respectively. Comparison with the known locations of human c-src (chromosome 20) and human c-Ha-ras1 (chromosome 11 short arm) suggests that the human and mouse homologs of these two viral oncogenes reside in conserved linkage groups. The c-Ki-ras gene on mouse chromosome 6 might reside also in a conserved linkage group, along with glyceraldehyde-3-phosphate dehydrogenase and triosephosphate isomerase. However, direct confirmation of this suggestion must await a demonstration that c-Ki-ras on mouse chromosome 6 is homologous to c-Ki-ras2 on the short arm of human chromosome 12.
