Recovery of 2R.2Sk Triticale-Aegilops kotschyi Robertsonian Chromosome Translocations

Robertsonian Translocations: An Overview of 872 Robertsonian Translocations Identified in a Diagnostic Laboratory in China

Robertsonian translocations (ROBs) have an estimated incidence rate of 1/1000 births, making this type of rearrangement the most common structural chromosomal abnormalities seen in the general population. In this study, we reports 872 cases of ROBs from 205,001 specimens karyotyped postnatally in a single accredited laboratory in China, including 583 balanced ROBs, 264 unbalanced ROBs, 9 mosaic...

Micro-Evolution in Grasshoppers Mediated by Polymorphic Robertsonian Translocations

This review focuses on grasshoppers that are polymorphic for Robertsonian translocations because in these organisms the clarity of meiotic figures allows the study of both chiasma distribution and the orientation of trivalents and multivalents in metaphase I. Only five species of such grasshoppers were found in the literature, and all of them were from the New World: Oedaleonotus enigma (Scudde...

Correlative Aspects of Imposition of Dormancy in Caryopses of Aegilops kotschyi.

Caryopses of Aegilops kotschyi Boiss. from different positions within the same spikelet differ greatly in their degree of dormancy. Imposition of this dormancy pattern is a correlative phenomenon within the spikelet, inasmuch as the uppermost developing caryopsis is least dormant and its development is associated with the dormancy status imposed on the lower (one or two) caryopses. Differences ...

Chromosome Translocations and Human Cancer1

quent findings that the great majority of human hematopoietic malignancies carry specific chromosomal alterations (3, 4) have suggested that such nonrandom chromosomal changes may be involved in the pathogenesis of human malignancies. This view, however, was not shared by many investigators outside the field of cancer cytogenetics, who regarded such chromosomal alter ations as epiphenomena of t...
