This chapter provides a general description of the types of genetic variation caused by transposable elements in animals and plants, and examines this variation within an evolutionary framework. It focuses on the variation induced by transposable ele

A deterministic population dynamics model of the spread of transposable elements (TE) in sexually reproducing populations is presented. The population is modeled by a three-parameter equation describing host reproductive capacity, population size and

To determine how population structure of the host species affects the spread of transposable elements and to assess the strength of selection acting on different structural regions, we sequenced P elements from strains of Drosophila willistoni and Dr

The retroelement Penelope isolated from Drosophila virilis has a very unusual structure and codes for reverse transcriptase and an endonuclease belonging to the UvrC type. As shown previously,Penelope is a key element in induction of the hybrid dysge

The Penelope family of retroelements was first described in species of the Drosophila virilis group. Intact elements encode a reverse transcriptase and an endonuclease of the UvrC type, which may play a role in Penelope integration. Penelope is a key

Sequences from the nuclear (nu) alcohol dehydrogenase gene, the nu 28S ribosomal RNA locus, and the mitochondrial cytochrome oxidase II gene were used both individually and in combined analyses to infer the phylogeny of the subgenus Sophophora (Dipte

It is generally accepted that the wide variation in genome size observed among eukaryotic species is more closely correlated with the amount of repetitive DNA than with the number of coding genes. Major types of repetitive DNA include transposable el

The Penelope element is the key element responsible for mobilization of other transposable elements in the course of hybrid dysgenesis in Drosophila virilis. Penelope has an unusually complex, highly variable organization in all studied species of th

The mobile element Penelopeis activated and mobilizes several other transposons in dysgenic crosses in Drosophila virilis. Its structure proved to be complex and to vary greatly in all examined species of the virilisgroup. Phylogenetic analysis of th

Species of the virilis group of Drosophila differ by multiple inversions and chromosome fusions that probably accompanied, or led to, speciation. Drosophila virilis has the primitive karyotype for the group, and natural populations are exceptional in
