Fig. 4: AdmixtureBayes29 population graph modelling of seven population groups representing major genetic horse lineages in Europe.
From: The genomic history of Iberian horses since the last Ice Age
a Population graph associated with the top posterior probability (0.565). b Population graph showing the second largest posterior probability (0.070). c Population graph showing the third largest posterior probability (0.064). No other population graphs account for more than 0.033 of the posterior distribution. Genetic drift estimates are reported along each branch, multiplied by 100, for readability, with values ≥ 10 highlighted in bold. Divergence nodes (n), exempt of admixture, are shown with ellipses coloured in dark grey, while admixture nodes (A) are shown with squares coloured in light grey, with percentages reflecting genetic contribution from the main contributing source. The fraction contributed by the second admixture source is the complement of this percentage to 100%. Branches associated with a proportionally larger admixture proportion are highlighted.
