At least 6 individuals per species were subjected to the C-banding and fluorochrome techniques.
The C-banding technique was performed according to Sumner (1972) with modifications proposed by Barros et al.
Results for C-banding revealed the presence of heterochromatin in the telomeric regions of the short arms: on a large metacentric chromosomal pair and on a sabmetacentric chromosomal pair.
stentina using cytogenetic approaches, such as C-banding, in situ RE banding, FISH with major ribosomal gene (ITS1), and telomere sequence (TTAGGG)n.
This C-banding pattern seems to be characteristic of spiders.
In spermatogonial mitosis, after C-banding, sex chromosomes have shown two different patterns.
The Andean specimens present C-heterochromatic blocks in most of their 22 chromosomes, whereas non-Andean specimens have only 4-7 autosomes with C-banding.
Using flow cytometry for DNA quantification and C-banding technique, we have determined the karyologic changes that have occurred during the dispersal of T.
analyses and the evolution of heterochromatin among arvicolid rodents.
Jellen, then a graduate student at the University of Minnesota, modified a staining technique called C-banding
The methodology used for the C-banding
was based on that of Sumner (1972) and sequential staining with the fluorochromes [CMA.
Afterwards, the application of differential staining techniques such as Ag-NORs for nucleolar organizer regions, C-banding
for heterochromatin or G-banding for individual chromosome identification allowed the identification of specific chromosome pairs in the karyotypes of bivalve species (see Thiriot-Quievreux 2002, for review).
