Abstract:

During the present study, mitotic chromosomes of two freshwater snails Gyraulus ladacensis and Indoplanorbis exustus were analyzed using ovotestis of specimens collected from the type locality (Nud pond Samba, Jammu), both belonging to class Gastropoda, order Basommatophora and family Planorbidae. The observed diploid chromosome number was 2n=36 consisting of 14 metacentric pairs, 03 submetacentric pairs and 01 subtelocentric pairs and 18 pairs of metacentric pairs respectively. Meiotic observations comprised leptotene, zygotene, pachytene, diplotene and diakinesis stages. Results of the present study have scientific and practical significance complementary to biochemical and molecular studies in animal taxonomy.
