  • a Observed and expected number of genes disrupted once, twice, and three or more times in collections of 191 mutants (Syngenta) and 129 mutants (Franzmann et al. 1995). Predictions assume that all genes mutate at equal frequency (Franzmann et al. 1995) and that either 500 or 1000 target EMB genes are present in the genome.

  • b Limited to class A, B, and Cs mutants as defined in the text.

  • c Mutants were mapped relative to visible markers and duplicate alleles were identified through complementation tests (Franzmann et al. 1995).
