Population rate parameters ΘC, ΘJ, and ΘA refer to the scaled effective population sizes (Ne) of var. sinensis (East China), var. arguta (South Japan), and the ancestral population, respectively. mC-J and mJ-C are the scaled migration rates forward in time from var. sinensis to var. arguta and vice versa. MC-J and MJ-C are the probabilities of migration from var. sinensis to var. arguta, per gene copy per generation and vice versa. 2NCMC-J and 2NJMJ-C are the effective migration rates (number of migrants per generation). t is the time since ancestral population splitting in mutational units.
All estimates include the per gene mutation rate u, which is equal to the geometric mean of the mutation rates of all the loci. ΘC, ΘJ, ΘA, mC-J, mJ-C, and t are scaled by the mutation rate, while NC, NJ, NA, 2NCMC-J, 2NJMJ-C and T are scaled by individuals or years.
