Introgression across sunflowers. (A) Fbranch statistic for annual species using the ASTRAL species topology. (B) The four best-supported TreeMix graphs with three admixture edges. A higher likelihood score is better. (C) The best-supported admixture graph from ADMIXTOOLS2 with three admixture edges. Branch lengths are not to scale. A lower score is better. (D) ABBA-BABA with the groupings [H. annuus OR H. argophyllus], other annual species, perennial species, Phoebanthus. Positive values indicate more ABBA counts. E) ABBA-BABA with the groupings H. maximiliani, other perennials, annual species, Phoebanthus.
