Point estimates are in bold typeface, and the high and low 90% Bayesian posterior probability densities are in parentheses.
*Second population used for comparison to CA weedy rice.
**Wild rice is O. rufipogon sampled from China.
*** Ne is the effective population size.
****NeM is the effective migration rate between populations (average number of migrants per generation G).
