^aNote.—Sites with at least two copies of the rarer variant present in the sample.

^bComposite genotypic r², the squared correlation of genotypic indicators at two loci in diploid individuals, was calculated using the “composite_LD” function submitted to the Bioperl project (Stajich et al. 2002) as described in Johnsen et al. (2009).

^cBased on the χ² test.
