Abstract excerpt
Nucleotide variation in the Acph-1 gene region was analyzed in a natural population of Drosophila subobscura from Bizerte (Tunisia). The lines studied differed in their gene arrangement for segment I of the O chromosome: 21 lines were O3+4+8, 21 were O3+4+23, and 3 were O3+4. According to chromosomal phylogenies, O3+4 is a central arrangement from which O3+4+8 and O3+4+23 originated. Strong genetic...
