Karyotype Analysis and Chromosome Banding
Nearly all methods of chromosome banding rely on harvesting chromosomes in mitosis. This is usually achieved by treating cells with tubulin inhibitors, such as colchicine or demecolcine (colcemid), that depolymerize the mitotic spindle and so arrest the cell at this stage. Excessively long incubations with Colcemid result in overcondensed chromosomes that band poorly and moreover some cell type...
متن کاملC-banding karyotype and relationship of the dipodids Allactaga and Jaculus (Mammalia: Rodentia) in Egypt.
The C-banding karyotype of the jerboas Allactaga tetradactyla, Jaculus jaculus jaculus, and Jaculus orientalis was described and interspecific relationships were discussed. Despite the conservation of a relatively small amount of C-heterochromatin located at the centromeric region of some chromosomes in all karyotypes, a striking loss of C-heterochromatin was clearly observed in J. orientalis. ...
متن کاملLimitations of G-banding Karyotype Analysis with Peripheral Lymphocytes in Diagnosing Mixed Gonadal Dysgenesis
Mixed gonadal dysgenesis (MGD) is an abnormal sexual differentiation syndrome usually presenting with ambiguous genitalia. Karyotype analysis is one of the essential components in the diagnosis of MGD and is conventionally done with peripheral lymphocytes by the G-banding technique. It is speculated that this conventional karyotype analysis has limitations since there are often difference in go...
متن کاملKaryotype and C-banding pattern of the domestic geese Anser anser populations (Aves: Anatidae) in Egypt.
The karyotype and C-banding pattern of domestic Greylag geese Anser anser anser populations collected from five localities in El Minia, Egypt, that have either whitish grey or white feather color patterns were described. All populations have a diploid number of 2n= 80 chromosomes. Of the 80 chromosomes, 10 pairs, including ZW chromosomes, were macrochromosomes and the remaining 30 pairs were mi...
