Inference of positive selection for alpha and beta genes in giant panda with different models.
Note: ω = dN/dS; p and q: parameters of beta distribution;
p0: proportion of sites with ω≤1;
ω2: value of ω for sites under positive selection.
*: posterior probability, P<0.95.
**: posterior probability, P<0.99.
