J. Genet. 92, 103–108

The caption for figure 2 appears under figure3, and the caption for figure 3 appears under figure 2. The captions should be interchanged. Figures 2 and 3 should also be in reverse order, i.e. the sequence alignment figure (printed and in online file as figure 3) should be figure 2, and the FISH figure should be figure 3.
