The complete mitochondrial genome of the stomatopod crustacean Squilla mantis

BMC Genomics

Table 4 Codon usage in nine malacostracan mitochondrial genomes. Columns indicate GC content and effective number of codons (N_c) for majority strand genes, minority strand genes, and all genes. The least squares linear regression equation and the coefficient of determination are also shown for each data set.
