Figure 5.—

Recombination breakpoints across the a1-interloop region of the mex haplotype. Exons of the a1 gene are shown as boxes. Short vertical lines represent sequence polymorphisms between the mex A1 Sh2 haplotype and the a1::rdt sh2 haplotype. The widths of the vertical lines are proportional to the numbers of polymorphic nucleotides. Subintervals are defined by sequence polymorphisms. Subinterval III-1 is not drawn to scale. Haplotype-specific primers are indicated by horizontal arrows. The numbers of recombination breakpoints that mapped to each subinterval are shown. Large InDeLs are indicated by triangles.
