Summary of the genotype of chromosomes XVI and IX in three SUSU translocants harboring complex rearrangements. As in Figure 4, numbers 2, 7, and 9 indicate SUSU2, SUSU7, and SUSU9 strains, respectively. The scheme contained in panel 9A shows a putative template switching-like mechanism that might be responsible for the rearrangement observed in SUSU9 (see results and discussion for more details).
