Patterns of naturally occurring restriction map variation, dopa decarboxylase activity variation and linkage disequilibrium in the Ddc gene region of Drosophila melanogaster.

Abstract excerpt

Forty-six second-chromosome lines of Drosophila melanogaster isolated from five natural populations were surveyed for restriction map variation in a 65-kb region surrounding the gene (Ddc) encoding dopa decarboxylase (DDC). Sixty-nine restriction sites were scored, 13 of which were polymorphic. Average heterozygosity per nucleotide was estimated to be 0.005. Eight large (0.7-5.0 kb) inserts, two small inserts...
