Male and female meiosis in the mountain scorpion Zabius fuscus (Scorpiones, Buthidae): Heterochromatin, rDNA and TTAGG telomeric repeats
All cytogenetically studied scorpions present male achiasmatic meiosis and lack heteromorphic sex chromosomes. In contrast, information about female meiosis in scorpions is scarce due to the difficulty of finding meiotic ...
Meiosis in a living crane fly spermatocyte [Meiosis II]
(The American Society for Cell Biology, ASBC Image & Video Library, 2011)
Heteropicnotic chromatin and nucleolar activity in meiosis and spermiogenesis of Limnogonus aduncus (Heteroptera, Gerridae): a stained nucleolar organizing region that can serve as a model for studying chromosome behavior.
Males of Limnogonus aduncus were found to have the sex chromosome system X0 and chromosome number 2n = 23 (22A + X0). Testis cells were stained with lacto-acetic orcein and silver nitrate so that changes in the morphology ...
A study of meiosis and spermiogenesis in the testicular lobes of Antiteuchus tripterus (Heteroptera : Pentatomidae)
(Czech Acad Sci, Inst Entomology, 2014)
Meiosis aspects and nucleolar activity in Triatoma vitticeps (Triatominae, Heteroptera)
Some aspects of both the nucleolar organizer activity and meiosis were studied in the testes of Triatoma vitticeps (Heteroptera, Triatominae). The techniques used included squashing followed by lacto-acetic orcein staining, ...
RNA reallocation during initial spermatic meiosis of Pseudonannolene tocaiensis Fontanetti, 1996
Toluidine Blue dye containing increasing concentrations of Mg2+ or Ca2+ can show loss of metachromacy at a certain concentration of the inorganic cation when staining DNA-protein complexes in vitro and in vivo. This process ...
