Chromosomal characteristics of Taolor's stream frog (Limnonectes taylori) (Amphibia, Anura) from Thailand
The somatic chromosomal architecture of the Taolor's stream frog ( Limnonectes taylori ) is described in relation with the location of nucleolus organizer region (NOR) and C-banding pattern. The 10 male and 10 female samples collected from Phitsanulok and Phayao province, Northern Thailand, wer...

| description | The somatic chromosomal architecture of the Taolor's stream frog (
Limnonectes taylori
) is described in relation with the location of nucleolus organizer region (NOR) and C-banding pattern. The 10 male and 10 female samples collected from Phitsanulok and Phayao province, Northern Thailand, were used for the study. Chromosome preparations were prepared from bone marrow following standard protocol. The results show that both male and female constitute the diploid chromosome number 2
n
= 22, and fundamental numbers = 44. No cytologically distinguishable sex chromosomes could be identified.
L. taylori
had the NORs adjacent to the subcentromeric on the long arm of chromosome pair 11. The C-positive heterochromatin blocks are distributed in the centromere of most chromosomes. The large heterochromatic blocks were found on short arm chromosome pair 7. The karyotype formula of
