Evolutionary relationships among Aiptasia lab strains. a NeighborNet phylogenetic network based on a concatenated set of 14,310 homozygous polymorphisms, ignoring heterozygous sites. Filled circles indicate genotypes of associated Symbiodinium algae (white: clade A, grey: clade B1, black: clade B2). The scale bar represents the number of differences per fixed polymorphic site. b Clustering analysis based on full 671,546 SNP callset, including heterozygous sites. Polymorphisms that were heterozygous in one sample received half the distance score of homozygous polymorphisms
