FIGURE 2. Summary of all possible genotype combinations using the Z- and the W-unique loci. The number and percentage of samples matching the conditions represented by the overlapping sets of the Venn diagram is shown in each area. The represented sets include homozygotes for F9A (a), heterozygotes for F9A (b), amplified for F7C (c), and not amplified for F7C (d). Females are depicted in purple (N=456) and males in green (N=457). Samples that could not be sexed are represented in the grey areas, while conditions not found in any sample are left empty.
