Fig 4. Immunological distance is not explained by genetic or physical distance.

Tanglegrams based on unweighted pair group method with arithmetic mean (UPGMA) trees of immunological distance, genetic distance, as F_st, and geographical distance among sites, where the scales are the relevant measures (S1, S2 and S3 Tables) of (A) immunological and genetic, (B) immunological and geographical, and (C) genetic and geographical distance among mice from the different sites. The site colour coding is as in Fig 1.
