ABC analysis of the nine historical scenarios describing the history of each population sampled in the secondary contact zone (Veneto).

Posterior probabilities are given, with their confidence intervals and associated type I and type II errors.
Note: 95% confidence intervals are indicated in brackets. Values in parentheses are the new posterior probabilities of scenarios re-analyzed in ABC due to the overlap between confidence intervals. The highest probability values are shown in bold typeface and indicate the best scenario. NW: North-West. NE: North-East.
CSE: Central and South-Eastern.
