Behavioral genetics of Drosophila ananassae
Authors: Shree Ram Singh, Bashisth N. Singh
Drosophila ananassae has a unique status among Drosophila species because of certain peculiarities in its genetic behavior. The most unusual feature of this species is its relatively high frequency of spontaneous male recombination. The results of studies on non-sexual behavior, such as phototactic responses, eclosion rhythm, .. Read More»

A technique to obtain fibroblast cells from skin biopsies of living bats (Chiroptera) for cytogenetic studies
Authors: Ricardo Moratelli, ClÃ?¡udio de Moraes Andrade and Jorge LuÃ?Âs Azevedo de Armada
We developed a procedure to obtain fibroblasts from bat skin. A small fragment of the ear is removed under ether anesthesia. This material is then cut up into small pieces and cultured in standard cell culture media. Very good quality chromosome preparations for cytogenetic studies are obtained in about three weeks. Secondary .. Read More»

Molecular cytogenetics in metaphase and interphase cells for cancer and genetic research,diagnosis and prognosis. Application in tissue sections and cell suspensions
Authors: Maria M�¼hlmann
As the pioneer among molecular cytogenetics techniques, fluorescence in situ hybridization (FISH) allows identification of specific sequences in a structurally preserved cell, in metaphase or interphase. This technique, based on the complementary double-stranded nature of DNA, hybridizes labeled specific DNA (probe). The probe.. Read More»
