Chromosomal inversion polymorphism of Drosophila subobscura from south-eastern part of Europe

Abstract

Five Drosophila subobscura populations from south-eastern Europe were investigated with respect to chromosomal inversion polymorphism. They belong to central European populations and their gene arrangement frequencies are in accordance with latitudinal variation observed in this species. The new complex gene arrangement A(2+8+9), found in one of the populations analysed, may be specific for the southern Balkan refugium. A general tendency of gene arrangement frequencies to exhibit some southern characteristics was found for some of the autosomal standard arrangements.
