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.

Figures in bold are referred to as ABS sites.
