Fig. 7.

Phylogenetic analysis of the Prdm10/15 subfamily. An ML tree is shown. Midpoint rooting has been used. A similar tree topology has been obtained by BI. Legend is as in figure 6. The duplication that likely took place during early vertebrate evolution is indicated. Nodes that define the monophyletic groups that allowed to position this duplication are also highlighted (Prdm10/Prdm15). These monophyletic groups are also found in ML trees constructed with several different species samplings (sampling 1: only deuterostome genes; sampling 2: only chordate genes; sampling 3: only vertebrate genes).
