Numbers of A. flavus L strain; lineage IB and IC isolates included in LD analysis for Figure 3 are shown in parentheses. Sample sequences based on six genomic loci (aflE/aflM, aflM/aflN, aflN/aflG, aflG/aflL, aflL/aflI, aflI/aflO) in A. flavus L, S and A. minisclerotigenes, and seven loci (aflB/aflR, aflS/aflH, aflH/aflJ, aflJ/aflE, aflE/aflM, aflG/aflL, aflK/aflV) in A. parasiticus.
Average pairwise differences between nucleotides across multiple cluster loci per site.
Watterson's estimator of the population-scaled mutation rate per site.
Tajima's D statistic is a measure of departure from neutrality.
Fu and Li D* statistic is a measure of the departure of the frequency spectrum from neutral expectations.
Number of segregating sites across multiple concatenated cluster loci.
Minimum number of recombination events across multiple concatenated cluster loci using RecMin.
Population recombination rate estimate per base pair.
Population mean recombination rate per site. First value is mean ρ and the numbers in parentheses are the lower and upper 95% confidence intervals, respectively.
Population sample data are fully compatible and recombination cannot be determined.
