Haptophyceae: Cluster 106

Number of sequences (GIs)5
Number of distinct taxon IDs (TIs)5
Shortest sequence378 nt -- Chrysochromulina polylepis small subunit ribosomal RNA gene, partial sequence.
Longest sequence562 nt -- Chrysochromulina sp. G3-53-A2 partial 18S rRNA gene, clone G3-53-A2.
Maximum alignment density1 0.888
Paralogous sequences present?2-
  1The fraction of non-missing nucleotides in an ideal alignment if no gaps had to be introduced. Low values indicate that cluster sequences are heterogeneous in length, with possibly only local homologies (for example, if one sequence is a complete mitochondrial genome, and others are single mt genes).
  2Assayed via a phylogenetic test of orthology (Sanderson et al., 2003), which checks whether a tree forcing all sequences from the same species to be a clade is significantly worse than one allowing them to be phylogenetically dispersed. If so, this is presumptive evidence of paralogy, lineage sorting, mistaken identification, or other causes of such incongruence.
