【 摘 要 】

The aim of this report was to detect full-sized P element sequences in eight strains of Drosophila sturtevanti populations from distant geographic regions and to assess the structural geographic variation among P element sequences. PCR analysis confirmed the presence of a putative complete P element in all strains. Southern blot analysis indicated bands shared by all strains, and bands restricted to geographically related strains. Parsimony analysis corroborated the hybridization pattern that reflected the geographic relationships.
