Abstract
The chromosome possessing two chromomycin A3 (CMA3) staining sites in lake trout (Salvelinus namaycush) was examined using FISH. All CMA3-bands in the karyotype contained ribosomal DNA (rDNA), including both sites on the double-CMA3 chromosome. One rDNA site on this chromosome was bordered by telomeric repeats, implicating a rearrangement in the origin of the second NOR.Keywords
