18. Karyotype and Banding Analyses of Oryzias celebensis (Oryziatidae, Pisces) in Cultured Cells

Abstract

With the fin-culture technique, detailed karyotype studies were undertaken in Oryzias celebensis, particularly following C-banding and silver staining procedures. The chromosome number was 36 in diploid consisting of 4 pairs of meta-, 2 pairs of submeta-, and 12 pairs of acrocentrics (NF=48). The “large” biarmed chromosomes seemed to be produced by the mechanism of Robertsonian fusion. The smaller submetacentric pair consisted of satellited chromosomes with NORs on their satellited regions. Four meta- and submetacentric pairs showed characteristic C-bands on their short arms. © 1981, The Japan Academy. All rights reserved.
