环纹游蛇
1.
The karyotypes of two species in Colubrinae from Fujian Sanmin were first reported by using the method of directly preparing chromosome with marrow cells, and they were found as : Natrix aequifasciata 2n =40,16(1M+5SM+2ST+8T) ·24m(♀); Sexual dimorphism of the chromosomes was represented by No 4 with ZZ/ZW mechanism, showing female heterogamety.
