Abstract

Karyological analyses of fish are important in terms of systematics and aquaculture . On this basis , the present study is aimed at analysing the metaphases of an ornamental fish , Gymnocorymbus ternetzi , for the presence of B chromosomes, an evolutionarily significant genetic element . Interestingly , the present study revealed the presence of B chromosomes in the metaphases, in the range of 0-2. The frequency of B chromosomes was found to be higher in females (1.06) than males (0.81). This is the first report on the existence of B chromosomes in G.ternetzi . Importance of B chromosomes are discussed.
