^aNumber of individuals from which Pto alleles were amplified and sequenced.

^bNumber of populations in sample.

^cSegregating sites and total sites in aligned sequences, excluding gaps.

^dAverage pairwise differences per synonymous site.

^eAverage pairwise differences per nonsynonymous site.

^fThe alleles peru505 and peru602 from individual 7232 of this population encoded putative pseudogenes and so this individual is not included in these estimates of π.

^gThe ratio of π_non/π_syn was not calculated for the self-compatible species because of the low number of segregating sites observed in these species.
