Figure 2.

An invasion of the P‐element in an experimental Drosophila simulans population visualized with DeviaTE (data from Kofler et al., 2018). We show the abundance and the diversity of the P‐element for four successive time points. The coverage was normalized to one million mapped reads and estimates of insertions per haploid genome ($\widehat{I}$) were calculated by relating the total coverage of the P‐element to the coverage of the gene rpl32. Note that the abundance of P‐elements as well as the number of internally deleted variants increases during the invasion
