Mitotic Abnormalities Induced by Silk Dyeing Industry Effluents in the Cells of Allium cepa
The results showed that silk dyeing industry effluents act as potential mutagens in Allium cepa root system and induced a wide range of mitotic abnormalities.
Studies on chromosomal characteristics of Ctenus indicus (Gravely 1931) (Araneae: Ctenidae)
Cytological evidence procured from the present study not only adds to the ever-growing list of the spider cytogenetic assessments but also offers as a baseline data towards establishing evolutionary relationships within this important group.
Karyology of Three Species of Indian Caecilians (Amphibia: Gymnophiona)
Three species of Caecilians, namely I. beddomei, I. ssp. and I. malabarensis were collected from different places of Karnataka and Kerala. Mitotic and meiotic chromosomes were prepared from liver and…
Chromosomal homology of Uraeotyphlus oxyurus group of species (Amphibia, Gymnophiona, Ichthyophiidae)
Chromosomal data seem to support the concept that two species groups exist in the genus Uraeotyphlus, with similar karyotypes with 2n=36 (FN=58).
Chromosome evolution in Indian Caecilians (Amphibia: Gymnophiona) and their phylogeny: A Review
- G. Venu
A new Indian species of Rhinophis Hemprich, 1820 closely related to R. sanguineus Beddome, 1863 (Serpentes: Uropeltidae).
A new species of the uropeltid (shieldtail snake) genus Rhinophis is described based on a type series of seven specimens from the Wayanad region of the Western Ghats of peninsular India, which had been misidentified as the phenotypically similar and parapatric R. sanguineus.
An Unusual Diet of Ichthyophis Caecilians (Amphibia:Gymnophiona)
The habitat of most caecilians is moist and porous soil that is rich in humus and organic matter, whereas members of the South American Typhlonectidae include aquatic and semiaquatic forms.

The gross karyotype and diploid number data support the recognition of two species groups within Uraeotyphlus, the monophyly of the oxyurus group, and the understanding that the ancestral diatriatan was more ichthyophiid- than uraeotYphlid-like.
