Purifying Selection Shapes the Dynamics of P-element Invasion in Drosophila simulans Populations
Anna Maria Langmüller, Benjamin C. Haller, Viola Nolte, Christian Schlötterer
The paper uses experimental evolution to study purifying selection on P-element invasion in Drosophila simulans, finding 73% of new insertions are under purifying selection with a mean selection coefficient of -0.056.
