From: Species and gene divergence in Littorina snails detected by array comparative genomic hybridization
Clustering of Littorina species and populations based on aCGH data. a) Neighbour-joining clustering by the number of divergent genes between Littorina species. Genes with significantly different hybridization signal were identified in comparisons of species and populations against L. saxatilis-Britain (applied cut-off q = 0.05). Numbers of divergent genes and their percentage of the total number of genes on the array are shown along the branches. b) Consensus tree of 20,000 bootstrap replicates based on all genes on the array. Numbers showed proportion of trees containing each cluster.
