Comparison of means ± standard deviations between MCMC (Markov chain and Monte Carlo) and TSL (two species likelihood) estimates (%) based on 26 intron sequences with and without GJF303 and 304.

aThe symbols of θ and τ stand for the nucleotide divergence due to the extent of polymorphism and the species divergence, respectively. θ = 4 Neµg and τ = tsµ, where g is the generation time in units of years, Ne is the effective population size, ts is the species divergence time and µ is the per-year nucleotide substitution rate.
bScale and shape parameters for gamma distributions of prior MCMC analyses are given in Table S2, and the result for set 1 is shown here.
cTwo different pairs of species were used for the TSL method. The estimates for the pair of chickens and green junglefowl are shown as θCG and τCG, and those for the pair of red and green junglefowls are indicated as θRG and τRG.
