Karyology of four Indian snakes
Cytogenetic studies were carried out on four species of Indian snakes viz Eryx conicus (Family Boidae), Naja naja naja (Family Elapidae), Vipera russelli and Echis carinatus (Family Viperidae) collected from Jammu region (J&K). Both E. conicus and N. n. naja show deviation from typical ophidian karyotype (2n=36), having 2n=34 (16 macroand 18 microchromosomes, NF=42) in E. conicus and 2n=38 (16 ...
متن کاملSome Observations on Plant Karyology and Investigation Methods
Karyology deals with the structure of cell nuclei, especially chromosomes. Cytology dealing with the study of cells in terms of structure also, function is known nowadays to mean only the study of chromosomes or nucleus and made synonymous with karyology wrongly. Cytotaxonomy means the application of cytological data to taxonomy. Cytotaxonomy studies the morphological and cytological characteri...
متن کاملKaryology of Plagiomnium . Ii
In a study of Plagiomnium undulatum from Poland, variability in karyotype formula and chromosome set length contrasted with high uniformity of chromosome number. Haploid chromosome number n = 6 was counted in 215 of 216 metaphases of plants originating from five populations, and n = 7 (6 + 1m) in one cell. The chromosomes were examined and ranked by total and relative length and arm ratio. The ...
متن کاملKaryology of Nine Lily Genotypes
Chromosome morphology was studied in lily genotypes L. candidum, L. × formolongi, L. henryi and L. pumilum, and cultivars ‘Alma Ata,’ ‘Expression,’ ‘Marco Polo,’ ‘Muscadet’ and ‘Star Gazer’ belonging to the horticultural group Oriental hybrids. All genotypes tested represented 2n = 2x = 24 chromosomes. Chromosomal markers were established after Feulgen and silver staining, from analysis of the ...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
