Abstract

Karyological characteristics in two species of Indian indotyphliid caecilian genus Gegeneophis reveal chromosome variations in morphology of chromosome arms but not in diploid number. In this case, pericentric inversions seem to predominate in karyotype reorganization. This change in chromosome morphology (pairs no. 2, 10 and 13) distinguishes each species karyotype.
