a Geographic distribution of sampled populations. Pie diagrams show supertype frequencies in populations. Supertypes are color-coded as in B (dots on branch tips). b Neighbor Joining (NJ) tree showing relationships between MHC class II alleles was rooted with stickleback sequence. c NJ tree showing relationships between mtDNA cytochrome b sequences (945 bp) from P. obscura, P. reticulata and P. wingei, rooted with sequences from. Micropoecilia picta and P. latipinna. Both NJ were constructed from matrices of nucleotide distances; bootstrap supports >70% are marked with asterisks.
