Table 4.

Nucleotide substitution analysis of a subset of genes in the duplication of chromosomes 11 and 12. A high confidence gene set has been selected for the calculation of synonymous (Ks) and non-synonymous (Ka) nucleotide substitutions. The genes are presented with their Ks/Ka values according to their chromosomal positions.
