Chromosomes of the bowhead whale (Balaena mysticetus linnaeus)
Thesis (M.S.) University of Alaska Fairbanks, 1979 The somatic chromosomes of the bowhead whale, Balaena mysticetus, are described for the first time using homogeneous staining and trypsin G-banding. The diploid chromosome number in all cells studied is 42. The bowhead karyotype retains many feature...
