CHROMOSOMAL POLYMORPHISMS OF CONSTITUTIVE HETEROCHROMATIN AND INVERSIONS IN DROSOPHILA [PDF]

Genetics, 1977
ABSTRACT 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.

Chromosome banding of two Litoria species (Anura, Hylidae) [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2013
This research was the first cytogenetic studies of green-eyed tree frog (Litoria genimaculata) and Nyakala frog(L. nyakalensis). The mitotic chromosomes were prepared directly from bone marrow after in vivo colchicine treatment andanalysed following ...

Chromosome study in Schistocerca (Orthoptera-Acrididae-Cyrtacanthacridinae): karyotypes and distribution patterns of constitutive heterochromatin and nucleolus organizer regions (NORs). [PDF]

, 2018
Chromosome analyses were performed in two grasshopper species of the genus Schistocerca, S. pallens and S. flavofasciata. Both species shared the same diploid number (2n = 23, X in males; 2n = 24, XX in females); and a con- served karyotype composed ...
