Abstract excerpt
Evolutionary processes can be inferred from comparisons of intraspecific polymorphism and interspecific divergence. We sequenced a 1.1-kb fragment of the cubitus interruptus Dominant (ciD) locus located on the nonrecombining fourth chromosome for ten natural lines of Drosophila melanogaster and nine of Drosophila simulans. We found no polymorphism within D. melanogaster and a single polymorphism within D....
