Table 2. Estimates of effective populations size (N e) from three independent methods.
Ne (field) | Ne (OU) | Ne (molecular) | FIS |
---|---|---|---|
7.75 (2–16) | 23.39 (4.68–32.75) | 23.60 (14.10–51) | 0.123 (P=0.01) |
Field, harmonic mean of number of breeding pairs with the range shown in parentheses. OU, Ne1/4h2s2 p/s2 step, where h2 is the trait heritability (set to 0.5, with 0.1–0.7 shown in parentheses), s2 p is the phenotypic variance of the sample and s2 step is the step variance. molecular, linkage disequilibrium method with Ne estimator with 95% confidence intervals shown in parentheses.
