A scheme of simulations. A) A scheme of individual based simulation running forward in time: Asexual complex is composed of ancestral sexual population of size N and d asexual demes of size N/d each. New clones are born at rate c to the first asexual deme, which is connected to other demes by a migration rate m according to the finite linear stepping-stone model. B) A scheme of coalescent simulation running backward time: Asexual complex is composed of one or more ancestral sexual populations (in the latter case, they are connected by migration rate m c ) and several clones with total population size N c distributed according to a broken stick model among clones. Looking backward in time, the clones either had a constant per generation probability P' of being founded by a single ancestor derived from a sexual progenitor (neutral model), or this probability raised per generation at rate [1 - (1 - f')α')]. Solid lines denote the branches in the genealogy, which evolved during the asexual phase. Only those are used for the pruned dataset. Dotted lines represent the sexual phase of sequence evolution.
