N (Analyzed) is the number of individuals analyzed with both software. For the Global analysis (structure), the entire dataset was used as a single input; for the Local analyses, multiple inputs were used (by location or joining closest locations when required, see Section 2). For newhybrids, N Assigned, number of individuals analyzed that were classified to any class. The class of the identified hybrids is also indicated by location, and the number of individuals per class is shown between brackets (F—L. fabalis, O—L. obtusata, F1 and F2 hybrids, and backcrosses to each parental class—BCF and BCO). The percentages were calculated in respect to the sample size (N Analyzed) for each location.
