FIGURE 1.

Non-tenera contamination rates within each individual sampled site. Palms and nursery seedlings genotyped as either wild-type (dura), homozygous mutant for any of the five identified SHELL gene MADS box mutations (pisifera) or heteroallelic for any two of the five mutations (pisifera) were classified as non-tenera. On the x-axis, numbers 1–13 indicate sampled regions according to Table 1. Letters represent each independent site sampled within the indicated region. Numbers in parentheses indicate the number of palms or seedlings genotyped per region/site. Error bars indicate 95% confidence intervals.
