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 ...

Karyology 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 ...

Karyology 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 ...

Earthworms newly from Mongolia (Oligochaeta, Lumbricidae, Eisenia)

Two new megadrile earthworms from the steppes, the first species wholly from Outer Mongolia, are ascribed to the partially parthenogenetic Eisenia nordenskioldi (Eisen, 1879) species-complex. Taxonomic justification of sympatric Eisenia nordenskioldi mongol and Eisenia nordenskioldi onon ssp. n. are supported by mtDNA COI barcodes. The unreliability of molecular differentiation based on voucher...
