Figure 2.

Schematic representation of AaNa_V haplotypes. Blue boxes indicate exons 20 and 21 with the intron between them, the latter used to classify the haplotypes as A (orange) or B (green). Sites 1011 and 1016 are represented by the variant wild-type (blue box) or mutant (red box). According to our hypothesis, there is a duplication in some populations, comprised of haplotypes 1011Ile + B + 1016Val and 1011Met + A + 1016Val. Dashed line suggests linkage of the haplotypes, but which one is upstream was not determined
