title: Phenotypic and genomic analysis of <i>P</i> elements in natural populations of <i>Drosophila melanogaster</i>
abstract: Abstract The Drosophila melanogaster P transposable element provides one of the best cases of horizontal transfer of a mobile DNA sequence in eukaryotes. Invasion of natural populations by the P element has led to a syndrome of phenotypes known as “P-M hybrid dysgenesis” that emerges when strains differing in their P element composition mate and produce offspring. Despite extensive research on many aspects of P element biology, questions remain about the stability and genomic basis of variation
