Figure 4From: Nuclear and mitochondrial data reveal different evolutionary processes in the Lake Tanganyika cichlid genus TropheusHomoplasy excess test. Potential hybrid and introgressed taxa identified by the AFLP homoplasy excess test. The boxplots illustrate the distributions of bootstrap support values obtained in 53 taxon-reduced bootstrap analyses for nodes, which experienced a significant increase in bootstrap support (marked by solid circles) upon removal of the following taxa: A, Tropheus "red belly"; B, the yellow coloured morphs near the Lufubu River estuary (samples from Lufubu, Ilangi, Inangu and Kabeyeye); C, samples from Livua; D, samples from Chisanze; E, samples from Katoto. The nodes are identified in Fig. 3.Back to article page
