(A) The posterior probability based on population assignment reveals individual exchange among 4 different bands and the bachelor group. Each box represents a social band. Each bar within the box represents a sampled individual from the band. Genetic characters of each band were estimated by unique allele frequencies, and marked by a corresponding color. The percentage of each color within the bar denotes the posterior probability of the individual origin. (B) Gene flow among the 4 breeding bands and GNG-AMB. The levels of gene flow are represented by θ and M value estimated by migrate. θ(4Neµ): mutation-scaled effective population size. M(m/µ): mutation-scaled migration rate; where m is the migration rate and µ is the mutation rate. The blue curves show gene flow from the breeding bands to the all-male band, whereas the green curves show the opposite gene flow from the all-male band to breeding band. The widths and the numbers beside the curves denote M values.
