(A) The number and lengths of shared segments within Settled Irish, within Traveller Irish, and between the groups. Left panel: The mean segment length; middle panel: the mean number of shared segments; right panel: the mean total sequence length (in cM) shared between each pair of individuals. (B) The number and lengths of shared segments within Traveller Group A, Traveller Group B, and between the groups. The format of the figure is as in (A).
