Title: <i>F</i>‐statistics of clonal diploids structured in numerous demes
Abstract: Abstract The expected apportionment of genetic diversity in diploid clonal organisms structured in numerous subpopulations is explored. Under the specific assumptions considered, corresponding, for instance, to clonal pathogens infecting a large number of hosts, the co‐ancestry between individuals within subpopulations is the only nontrivial quantity. Thus the population structure can be fully described either by F ST or F IS , as F ST = – F IS /(1 − F IS ). We show that, for most of the parameter space considered, including simulations where equilibrium is not reached and/or where homoplasy is high, the number of effective migrants is most accurately estimated as Nm = –(1 + F IS )/4 F IS . We further propose a criterion to test for the absence of cryptic sexual reproduction based on the F ‐statistics F IS and F ST , which is applied to three previously published empirical data sets.
