* Posterior probability that each individual has recent ancestry (parental or grandparental) from the species opposite that identified by the AFLP analysis.

Two STRUCTURE assignment and ancestry analyses were performed, one with prior population information assigned and the second with putative hybrid population identity set as unknown to examine alternate parentage contributions. Last row identifies fifth possible hybrid discovered by the analysis.
