Results of positive selection calculation are visualized onto 3D structure of PPP2R5C, HEXB, GBP1 and CASP8 pig proteins. The color scale from light to dark green represents purifying selection, while orange and red represent positive selection with posterior probabilities greater than 95% or 99%, respectively. The orange arrow points to the serine at position 427 of GBP1 protein that is under positive selection.
