Abstract
We used quinacrine hydrochloride and chromomycin A3 staining techniques to examine chromosome-banding polymorphisms in lake trout Salvelinus namaycush from seven wild populations and two hatchery stocks from the Great Lakes region. Although considerable variation in the number of bands occurred among individuals examined by both staining techniques, banding patterns were constant for all cells of a given individual. The populations were differentiated into three groups on the basis of the number of chromomycin A3 bands: a group from the northern shores of Lakes Superior and Huron and the inland lakes north of Lake Superior; a group from the southern shore of Lake Superior; and a group that comprised one wild population and one hatchery stock from Wyoming that were both originally transplanted from a Lake Michigan stock. Each population within these three groups had a unique distribution of chromomycin A3 bands on specific chromosomes. Results for a given population were consistent when...This publication has 1 reference indexed in Scilit:
