Haplotype networks of Seriatopora hystrix (mtDNA) and the associated Symbiodinium (ITS2). Unrooted haplotype networks of (a) Seriatopora hystrix (mtDNA) and (b) the associated Symbiodinium (ITS2). Colours indicate host and symbiont genotypes that together constitute the four different ecotypes: B-ecotype, U-ecotype, D1-ecotype and D2-ecotype, which are grouped together by the shaded ovals. Dagger (†) indicates a 51bp tandem repeat that was excluded from the analysis.
