Distinctive natural allelic polymorphisms of TvQR1 and TvPirin. (A) Sliding window analysis of nucleotide diversity of TvQR1 and TvPirin. Solid and dashed lines are silent (synonymous and intron) and non-synonymous nucleotide diversity, respectively. Shaded regions indicate exons. (B) Minimum estimates of recombination across TvQR1 and TvPirin. Within each line, at least one recombination event was detected by the four-gamete test. Shaded regions indicate exons.
