Figure 4

Alignment of the putative amino acid sequences of 34 random exon 2 alleles in the Eurasian Coot. Dots indicate identity with the top sequence (Fuat-DAB*109). Crosses indicate sites known to interact with antigens in the human MHC class II molecule (Brown et al. 1988). Black asterisks and black triangles mark sites under pervasive positive or purifying selection, respectively. The number of asterisks or triangles at a given site is related to posterior probability values (*>0.90, **>0.95, ***>0.99).
