Isolation model (IM) for Scots and loblolly pines.

aNumber of polymorphisms detected in loblolly pine sequences (N = 27–32).
bNumber of polymorphisms detected in Scots pine sequences (N = 2).
cNumber of shared polymorphisms between loblolly pine and Scots pine.
dNumber of fixed differences between loblolly pine and Scots pine.
eSum of the chi-squared values for each class of variation per locus.
fSignificance of the chi-squared values.
*Indicates P<0.05 for the significance of the results, after Bonferroni correction for multiple testing. Bonferroni corrected threshold for α = 0.05 is 1.85×10−3.
The results from comparing observed values to 10,000 simulations under the fit model (see text) are also presented. P-values reported in the table below can be multiplied by the number of loci analyzed (27) to provide a Bonferroni correction for multiple tests. Loci that deviated from the fit model are shown in bold.
