Comparative karyotypic studies on three species of the subfamily viverrinae in Thailand

Abstract

Comparative karyotypic studies on 3 species, large-spotted civet (Viverra megaspila), large Indian civet (V. zibetha) and small Indian civet (Viverricular indica) using conventional staining and G-banding patterns were investigated. Blood samples taken from Khao Khiew and Dusit Zoo were examined using lymphocyte culture techniques. The results indicate that the number of diploid chromosome of large-spotted civet, large Indian civet and small Indian civet are 38, 38, and 36, respectively. The fundamental number (NF) are 72 for female and 71 for male, 72 for female, and 70 for female and 69 for male. The type number of autosomes, metacentric, submetacentric, acrocentric and telocentric chromosomes are 10-10-12-4, 10-10-12-4 and 10-12-10-2, respectively. Chromosome pairs 15, 17 and 17 are satellite chromosomes. The X and Y chromosomes are submetacentric and telocentric for large-spotted civet and small Indian civet, whereas. The X and Y chromosome are not known for large Indian civet. In addition, G-banding techniques show that there are 143, 148 and 145 banding patterns which are able to chromosomal classify of these 3 species. © 2006 The Japan Mendel Society.
