Table 3. Numbers of mutants in each genome of the SBE3 gene.
| Position of mutation | Genome allele | ||
|---|---|---|---|
| WT-A | WT-B | WT-C | |
| Site A | 9 | 16 (8) | 5 |
| Site B | 7 | 17 (8.5) | 8 |
| Others | 2 | 7 (3.5) | 13 |
| Total | 18 | 40 (20) | 26 |
The number of mutations found at each site was counted. The position of mutation was determined by the nucleotide sequences of each mutant. Numbers in parentheses indicate those of an estimated single allele of WT-B because of two alleles in the genome.
