Figure 3

Effect of switching from outcrossing to self-fertilization. The two figures represent typical dynamics of a TE family simulated within a selfing population which has outcrosser ancestors. The initial population was originally a strict outcrossing population (N = 2000), already invaded by TEs, in which an abrupt transition to self-fertilization is performed. The new population thus has a historical background with numerous copies, both autonomous and non-autonomous, and few domesticated insertions (P_{s > 0}= 0.01%). Very rapidly after the transition to selfing (generation 0), almost all insertions become homozygous (even number of copies in all lineages). TEs are then systematically lost after few hundred generations, including adaptive insertions.
