Python molurus molurus (Linnaeus, 1758) is 2000 m above sea level. The Indian Rock Python is a nocturnal snake that inhabits estuarine mangrove forests, arid scrub jungle, rain forests, feeds on mammals, birds, and reptiles, but seems to prefer mammals (Daniel 2002). Females lay them (Daniel 2002). Leucism is a form of albinism in which the eyes, legs and beak are normally pigmented, whereas the skin or feathers have either reduced coloration or lack it entirely (Sage 1962). Leucism or partial albinism (McCardle 2012) is controlled by a single recessive allele (Owen and Skimmings 1992), but albinism is caused by several genes (Summers 2009). Inherited color defects, such as albinism and leucism, are well known in several animal species, including
SummaryThe karyotype and C-banding analysis of somatic metaphase chromosomes were attempted on 3 species of Indian frogs (Rana curtipes, R. temporalis, R. malabarica) which are distributed in the Western Ghats, Southwest India. All had 2nϭ26 chromosomes with invariably 5 pairs of large and 8 pairs of small chromosomes. Metacentric and submetcentric chromosomes were found in the complement, the former more common than the latter. A secondary constriction with a prominent satellite in the short arm of nos. 10 and 12 chromosomes are unique only in R. curtipes. The Cpositive telomeric bands were localized in the short arms of nos. 9 and 10 chromosomes of R. temporalis. Non-centric C-positive bands were observed in the distal half of the long arm of no. 10 chromosome of R. malabarica. None of the 3 species had an identifiable sex chromosome. There were variations in the centromeric position and secondary constriction of chromosome pair nos. 2, 3, 4, 5, 9, 11 and 12. These variations might have arisen due to pericentric inversions. It seems likely from the inversion studies that R. curtipes and R. temporalis are chromosomally more closely related than R. malabarica. Comparative account of karyotypes are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
