Replication “timing” profiles for chromosome 12 from an S. cerevisiae/S. bayanus hybrid. Replication profiles are drawn as described in the legend to Figure 2. (A,C) Profiles are shown for the S. cerevisiae and S. bayanus chromosomes from the hybrid. (B,D) Hybrid data are shown superimposed on data from the respective nonhybrid diploids. (E) Smoothed data from the S. cerevisiae and S. bayanus chromosomes from the hybrid are shown projected onto the S. cerevisiae coordinates to aid comparison.
