| Abstract: | Karyotypesand Ag-NORs of 3 species; Elaphe prasina, E. davadi and E. radiata femalewere reported.The karyotypes of E. prasina and E. davadi were 2n=8V+6sV+2I+20m (male) and2n=7V+7sV+2sI+20m (female), respectively. The Karyotype of E. radiata was2n=6V+3sV+2sI+5I+24m. Considering other species in Elaphe, the results suggested that ① the numbers and morphologicalstructures of E. prasina and E. davadi were homomorphic as those of most species in thisgenus; ② Sexchromosomes of the 3 species were heteromorphic which resulted from Z and W differences inchromosome sizes and centromere positions; ③ The numbers and positions of NORs in the 3 species weredifferent. ④ E.radiata was distinct at chromosomal level. The differences in its karyotype, sexchromosomes and the NORs may suggest abrupt chromosomal event in the evolution of E.radiata. ⑤ Thespecies in Elaphe could be divided into 4 groups including E.radiata as a specific group.Fig 1, Tab 2, Ref 18 |
