- Abstract
The current study analyzed the chromosomal karyotype of Quasipaa spinosa David, 1875 from Hunan Province, China. The karyotype, C-banding, BrdU -banding pattern were characterized using direct preparation of bone-marrow cells and hemocyte cultures. The findings indicated that Q. spinosa was a diploid species (2n = 26) that lacked heteromorphic chromosomes and secondary constrictions. C-banding analysis revealed an abundance of positive signals in the centromere regions, while the BrdU -banding pattern showed three phases in both male and female, occurring consistently and in chronological sequence during S-phase. Notably, there was no asynchronous replication in the late phase. This study enhanced our understanding of the karyotypic structure of Q. spinosa by conventional cytogenetic techniques, thus providing essential scientific insights into the cytogenetics of Q. spinosa.
