Figure 5From: Early vertebrate chromosome duplications and the evolution of the neuropeptide Y receptor gene regionsA-F – Phylogenetic analysis of neighboring gene families. A-F. Examples of the phylogenetic relationship for six additional neighboring gene families A (MAX), B (NKR), C (OGDH), D (PX19), E (SORB) and F (TSPAN). Trees were constructed and visualized in the same way as in Fig. 4.Back to article page
