Codon-usage weighted by the nucleotide base bias defines our score called the Codon-Impact-Parameter. This score is used to obtain phylogenetic relations amongst the 47 Ectocarpales. We compare our classification with the ones done earlier.GenomicsPopulations and EvolutionWeighted-Codon-Usage Based Phylogeny In Ectocarpalestext
