Fig. 3

A schematic comparing the genomic organization of Brachyury and its neighboring genes within scaffolds/chromosomes. Presence and transcriptional direction of the genes are shown with boxes. Boxes of the same color or protein names show orthologous relationships (or paralogous within a given species) while white boxes show no orthologous relationship to any known proteins. Note that genes indicated in blue boxes with black slanting lines share domains with a comparable or similar DNA sequence. Divergence times are based on TIMETREE database [42], except for nodes with asterisks (no estimate)
