Quantitative Cladistic Analyses of Chromosomal Banding Data Among Species in Three Orders of MammalPrimate chromosomes have been shown to stain differentially against a rodent background in somatic cell hybrids using the alkaline Giemsa (G-ll) staining procedure (Bobrow and Cross, 1974). Incorporation of tritiated thymidine or bromodeoxyuridine (BrdU) followed by the appropriate staining allows f

(1970) and the advent of gene cloning through recombinant DNA techniques, it has become possible to locate the positions of specific genes and to survey the distribution of repetitious elements with considerable accuracy. As a consequence, we probably know

The segregation of RFLP markers can be monitored in progeny from controlled genetic crosses and, by using standard genetic analysis, linkage group

Book 1988tance. As genetics became more refined in the early decades of the 20th century the genes-on-a string model of chromosomes developed and greater emphasis was placed on the further dissection of these structures. As a result, in the 1980‘s the reductionist approach is reaching a crest as extensive r

Chromosomes and Kinetochores do More in Mitosis than Previously Thought,s made clear in the 1930’s when it was recognized that a site on each chromosome — the kinetochore or centromere — is essential for normal chromosome movement in mitosis and meiosis (review: Schrader, 1953). Since then, one certain role of the kinetochore has been identified: the mechanical attachme
