| Abstract: | The diploid number of lygosoma indicum is 30, consisting of 6 pairs of matacentric macrochromosomes, 8 pairs of spot microchromosomes and 1 pair of sexchromsomes, chich are heteromorphic in male, isomorphic in female. Sex determination is XY.The dear C-bands wer found in the centromeric positions of the macrochromsomes and sexchromosomes, 1 pair of Ag-NORs are located in the microchromosome No. 8.The morphologica of the karyotype and Ag-NORs between lygosoma indicum and Eumeceschinesis, Sphenomerphus indicum were compared, Lygosoma indicum is considered a more primitive species than the others in Scincidae. |
