细胞遗传学分析的分析和Ag-NORs八种teleostean鱼类,也就是说,鳍胶(鲭科),Valamugil speigleri(鲻科),Balantiocheilos melanopterus, Amblypharyngodon microlepis(鲤科),Lepidocephalichthys guntea(鳅科),Pangasius hypophthalmus (Pangasiidae) nandu nandu(南鲈科)和Ompok bimaculatus (Siluridae)。其中,L。guntea(男性ZZ:女性佐薇)和o . bimaculatus(男性X1X1X2:女性X1X1X2X2)形态可识别性染色体。核仁组织区(古称)位于晚期一对近端着丝染色体的着丝粒区域(Tc, 1) T。胶和V。speigleri (2 n = 48),在短臂(Tp)的一对亚中间着丝粒染色体在B。melanopterus (2 n = 50;6号),在一个。microlepis (2 n = 50;1)和P。hypophthalmus (2 n = 60;1号),在整个短臂(p)一对亚中间着丝粒染色体的L。guntea(第一; male, 2n=52, female 2n=51), at the longer arms of one pair of interstitial sub-terminal (Ist –q, No.1) and at terminal regions of one pair of submetacentric chromosomes (Tq, No.10) in N.nandus (2n=48) and at shorter arm of one pair of submetacentric chromosomes (Tp, No.4) in O.bimaculatus (male 2n=41, female 2n=42). The significance of the study has been discussed in the light of other previous studies and their karyotypic evolution.
