Summary of the gene conservation analysis. (A) Distribution of 2308 unique P. lamarckii ESTs. Genes were classified into groups based on their pattern of putative orthology with genes in other major metazoan groups. (B) Illustration of gene loss in the evolution of metazoan genomes in reference to P. lamarckii orthologues. Refer to Methods for further explanation of classification and gene loss characterization.
