Analysis of meiosis and non-random bivalent formation in desynaptic mutants of Pennisetum americanum (L.) LeekeSpringer Science and Business Media LLC - Tập 59 - Trang 157-160 - 1982
M. V. Subba Rao, P. Sukhadev, J. V. V. S. N. Murty, V. Manga
Meiotic behaviour of induced desynaptic mutants of Pennisetum americanum (L.) Leeke in general was described. The frequency distribution of bivalents in induced desynaptic mutants was compared with that expected on the basis of the binomial series. The deviation from the binomial distribution was tested as to its conformity with models based on intra-and intercellular differences in bivalent forma...... hiện toàn bộ
Analysis of different banding patterns and late replicating regions in chromosomes of Allium cepa, A. sativum and A. nigrumSpringer Science and Business Media LLC - Tập 71 - Trang 39-46 - 1986
F. Cortés, P. Escalza
Different banding procedures and preferential Giemsa staining of late replicating DNA-rich regions were carried out in metaphase chromosomes of three species belonging to different sections of the genus Allium (A. cepa, A. sativum and A. nigrum). The banding, as well as the late replicating patterns were species-specific. The late replicating pattern proved to be, in all cases, the more detailed, ...... hiện toàn bộ
Distribution of transposable elements in Drosophila speciesSpringer Science and Business Media LLC - Tập 105 - Trang 43-62 - 1999
Christian Biémont, Géraldine Cizeron
We present a global analysis of the distribution of 43 transposable elements (TEs) in 228 species of the Drosophila genus from our data and data from the literature. Data on chromosome localization come from in situ hybridization and presence/absence of the elements from southern analyses. This analysis shows great differences between TE distributions, even among closely related species. Some TEs ...... hiện toàn bộ
