Number of isolates that produce B (B1+B2) AFs only.
Number of isolates that are B1 dominant (G1/B1≤0.5).
Number of isolates that have equivalent amounts of G1 and B1 (0.5<G1/B1<2.0).
Number of isolates that are G1 dominant (G1/B1≥2.0).
Samples either uncorrected or haplotype corrected (bold type) based on four genomic loci: aflM/aflN, aflW/aflX, amdS, trpC.
Numbers in parentheses refer to number of isolates (uncorrected) or haplotypes (corrected) examined for each genetic scale.
Probability of a binomial test (two-tailed). Test was performed on the raw data.
Three isolates are non-aflatoxigenic, producing neither B nor G aflatoxins.
