Maximum Likelihood summary tree, rooted using the outgroup H. klunzingeri. Fish genotyped to actual taxon using either nuclear dataset bear the same symbols as used in Fig. 2, while fish identified solely on morphological criteria are denoted in blue font (although all HB × HX* and many HA × HX* fish display the ‘Lakes’ phenotype, some HA × HX* fish are phenotypically similar to HA). The actual haplotype tree for the HX clade is shown in the inset.
