Figure 2

Comparison of TinT relative times of activity and the main divergences of the galliform tree. (A) Cumulative TinT of CR1 elements on a relative timescale during gamebird evolution. The graph shows the cumulative maximum probabilities of activities for nested CR1 retropositions that were fixed in the ancestral lineage of the chicken genome. (B) A simplified galliform tree showing the main divergences from the lineage leading to the chicken (in red). The CR1 subtypes depicted above the various branch points were identified by presence/absence analysis in species on the corresponding internal branches in this study and by Kaiser et al. [12]. The elements within the shadowed areas connecting (A) and (B) that were apparently active on specific branches of the galliform tree were dominating in corresponding peaks of the cumulative TinT graph.
