Effective population sizes of Ficedula albicilla, F. parva and their common ancestor are denoted by Ne(FIAL), Ne(FIPA) and Ne(anc), respectively. M1 indicates the number of individual per generation migrating from F. parva to F. albicilla and M2 indicates the migration in the other direction. t indicates the divergence time between the two species in the unit of years. These analyses are based on 15 introns, 17 introns and 17 introns plus one exon, respectively. HiSmth indicates the value of the highest posterior probability after being smoothed using surrounding points. 95Lo indicates the value to which 2.5% of the total distribution lies to the left. 95Hi indicates the value to which 2.5% of the total distribution lies to the right.
