Genetic diversity and selective neutrality tests for PgHd3a.

aS: number of segregating sites. bSin: number of singletons. cθ: Watterson estimator of sequence diversity per site, π: average number of differences per site between two sequences, the diversity of the candidate genes was estimated for the non-coding (nc), synonymous (syn) and non-synonymous (nsyn) sites. dNumber of lineages with at least one singleton. eD and F* were calculated for the simulation using parameters randomly drawn from the posterior distribution. fP-values were computed for unilateral tests as P than the observed value according to the sign of the statistics without correction for multiple tests.
