The gene clusters encoding 18S + 28S and 5S rRNA in the dog (Canis familiaris) have been localized by using GTG-banding and fluorescence in situ hybridization. The 18S + 28S rDNA maps to chromosome regions 7q2.5-->q2.7, 17q1.7, qter of a medium-sized, not yet numbered autosome, and Yq1.2-->q1.3. Our data show that there is one cluster of 5S rDNA in the dog, which maps to chromosome region 4q1.4.
利用GTG显带和荧光原位杂交技术，对犬（犬属）中编码18S + 28S和5S rRNA的基因簇进行了定位。18S + 28S rDNA定位于7号染色体区域7q2.5→q2.7、17号染色体区域17q1.7、一条中等大小、尚未编号的常染色体的qter以及Y染色体区域Yq1.2→q1.3。我们的数据表明，犬中有一个5S rDNA基因簇，定位于4号染色体区域4q1.4。
