Upsalienses I. 150 The chromosomes have individuality or genetic continuity from one cell generation to another. This conception..may be considered as the foundation of all comparative karyology. 1948 W. Andrew tr. E.D.P. de Robertis's Gen. Cytol. vii. 134 There was considerable progress in karyology, which is a branch of cytology dealing with the nucleus or karyosome, to the detriment of the study of the cytoplasm or cytosome. 1965 Jrnl. Nat. Cancer Inst. (U.S.) XXXV. 766/1 This..indicates a significant difference between the general karyology of the normal cell and of the tumor cell population. 1970 Cytologia XXXV. 294 (heading) Karyology of Sequoia sempervirens: karyotype and accessory chromosomes. 1971 Daily Colonist (Victoria, B.C.) 24 Dec. 4/2 Karyology, or the study of the number, shape, and size of chromosomes, is Dr. Wiens' specialty. |
