Reversible phenotypic switching can be caused by a number of different mechanisms including epigenetic inheritance systems and DNA-based contingency loci. Previous work has shown that reversible switching systems may be favored by natural selection. Many switches can be characterized as “on/off” where the “off” state constitutes a temporary and reversible loss of function. Loss of function phenotypes corresponding to the “off” state can be produced in many different ways, all yielding an identical fitness in the short term. In the long term, however, a switch-induced loss of function can be reversed, while many loss of function mutations, especially deletions, cannot. We refer to these loss of function mutations as “irreversible mimics” of the reversible switch. Here we develop a model where a reversible switch evolves in the presence of both irreversible mimics and metapopulation structure. We calculate that when the rate of appearance of irreversible mimics exceeds the migration rate, the evolved reversible switching rate will exceed the bet-hedging rate predicted by panmictic models.
