Summary statistics for Atlantic menhaden ( Brevoortia tyrannus) and Gulf menhaden (B. patronus) collections by locus. Number 
of individuals (n), number of alleles (a), allele size range (as), allelic richness (R s ), observed heterozygosity (H 0 ), expected hetero- 
zygosity (H e ), and probability of conformance with Hardy-Weinberg Expectations (HWE). ** indicates significant deviation from 
the expectations of HWE after correction for multiple tests (initial a=0.05, k=8).
