FIRST KARYOLOGICAL ANALYSIS OF AN ENDEMIC FISH, ZAGROS TOOTH-CARP, APHANIUS VLADYKOVI COAD, 1988 (ACTINOPTERYGII: CYPRINODONTIDAE) FROM IRAN

Abstract

The karyotype of Zagros tooth-carp, Aphanius vladykovi (Coad) has been investigated byexamining metaphase chromosomes spreads obtained from gill epithelial and kidney cells. The diploidchromosome number of this species was 2n=48. The karyotype consisted of 8 submetacentric and 40subtelocentric chromosomes (8Sm+40 St). The arm number (NF) was 28. Sex chromosomes werecytologically indistinguishable in this tooth-carp.
