)Rate of migration between the two populations. Migration is implemented such that with probability m (migration rate) one of the two parents of a new offspring is from the other population, with probability 1-m both parents are of the focal population.
option to stop at a critical FST value , default is FALSE
the critical fst value to stop, if
stop_simulation_at_critical_fst is TRUE
vector of population sizes, one size for each population
A list describing the initial frequency of each ancestor in each population. Each entry in the list contains a vector with the frequencies for all ancestor. The length of the vector indicates the number of unique ancestors. If a vector not summing to 1 is provided, the vector is normalized.
The number of generations after which the simulation has to check again whether the critical Fst value is exceeded
Number of individuals to be sampled at random from the population to estimate Fst
Number of markers to be used to estimate Fst
Are the markers to estimate Fst randomly distributed, or regularly distributed? Default is TRUE.
list with migration associated settings. To be used to pass on migration settings to simulate_admixture.
