Fig. 5

CBDAS allele frequency variation among populations with >/= 10 resolved genotypes. Population localities are indicated by small black circles. Pie-charts display the proportion of functional (B1; white) and non-functional (B2; black) CBDAS alleles observed within populations among individuals for which a CBDAS genotype was resolved. Populations not linked to a chart are fixed where fB1 = 1.
