[i] The chromosomes were composed of the SfiI elements and MRSs. The size of each SfiI fragment is shown in Tables 1and 4. The total size of the SfiI fragments is shown asSfiI total. The sizes of the gaps shown in Table 2, 3 and 5and Figures 5 and 6 were totalled in each homologous chromosome and are shown as gap total. The gap size is approximately, but not exactly, the size of the RPS. To reconcile the total sizes of the SfiI fragments and gaps to the chromosome size, the appropriate gap sizes were chosen.
