Supplementary table 1: Chromosomal segments identified after chromosomal alignments between chicken,
turkey and zebra finch. Previously FISH-mapped chicken and zebra finch BAC clones overlapping segment
locations were used to assess whether the rearrangement was consistent with physical marker order. a Segment
not present.
Supplementary table 2: Segment ends involved in rearrangement pathways predicted by MGR
19
. The number
of times a segment end is at a breakpoint is noted for three pathways: chicken-turkey ancestor to (1) chicken, (2)
turkey and (3) zebra finch. Recurring breakpoints are noted as to whether they occur only within one pathway, or
more than one pathway. Note that in reality the pathway to zebra finch represents two lineages.
Supplementary table 3: Reconstructed chicken-turkey ancestral organisation, and optimal pathways to each
modern species' organisation as determined using the MGR tool on the GRIMM web server.
Supplementary table 4: Comparison of repetitive content for classes of repeats between breakpoint regions and
segments, using the breakpoint data from chicken.
