Header rows show the maximum and minimum proportions for each category of hybrid simulated, where e.g. bx3_A.a is a third backcross generation to An. arabiensis. X-diagnostic marker classification of each sample is shown in the far left column followed by the BAPS estimate of the proportion of each species present in the sample and associated probability that the sample is not mixed. A ‘1’ under any category indicates the sample could represent a member of the hybrid category based on simulations. The far right column is a summary of plausible hybrid categories for each sample, where e.g. bx1+ is a backcross of the first or subsequent generation.
