^aNumber of variable sites.

^bNucleotide diversity per bp.

^cSummary statistic of the allele frequency spectrum.^25,30

^dComposite likelihood estimator of the population recombination rate parameter (4Nr) based on a model of gene conversion in which conversion events are twice as common as crossover events and the conversion tract length is geometrically distributed with mean 500 bp.
