Genetic architecture of the hybrid zone. Maximum-likelihood estimates of molecular hybrid indices (MLE(h)) and their associated confidence intervals based on band frequencies for all individuals (both parental species and their hybrids) sampled across the hybrid zone. The hybrid index (h) ranges from zero to one, corresponding to pure individuals of Ophrys lupercalis (the other parent species) and O. arachnitiformis (the reference species), respectively.
