Chromosomal polymorphisms of constitutive heterochromatin and inversions in Drosophila.
A simple technique for preparing mitotic metaphases from a larval ganglion of Drosophila is described. Parallel examination of polytene and metaphase chromosome groups shows that inversion polymorphism in chromosome 3 of D. recticilia from East Maui (Hawaii) manifests a one-to-one correlation with a metaphase karyotype polymorphism due to the presence of an extra heterochromatic portion. These ...
متن کاملMorphology of Human Insula in Iranian Population and its Relationship with Sex, Age, and Handedness: an Imaging Anatomical Study
Background and Aim: Topography of the human insula has occasionally been studied in different populations. The purpose of this study was to evaluate the morphology of human insula in Iranian population and its relationship with sex, age, and handedness via magnetic resonance imaging. Methods and Materials/Patients: In our study, 380 normal magnetic resonance imaging were enrolled. The number...
متن کاملVariablity of chromosomal radioadaptive response in human lymphocytes.
Background : There are growing evidences for chromosomal radioadaptive response in human lymphocytes . Highly variable inter- and intra-individual responses have been reported. Some individuals are non-responders and even in some donors the frequency of chromatid aberrations induced by a challenge dose increases by pre-exposure to an adapting dose. It has been proposed that the lack of radioada...

15 صفحه اولQ Band Chromosomal Polymorphisms in Lake Trout
Q banding of chromosome preparations from lake trout revealed the presence of heteromorphic quinacrine bright bands on several chromosomes. All of the metacentric chromosome pairs can be distinguished on the basis of number, position and intensity of the quinacrine bright bands and chromosome size. These bands appear to represent heterochromatin, since they are darkly staining with the C band t...
