The ratios of the codon frequencies for the amino acids coded by four or by six codons in the genetic code exhibit a correlated behaviour for 29 biological species. The analyzed species are such that the whole codon number, determined from the available coding sequences, is larger than about 100 000. This correlation fits naturally in the framework of the crystal basis model of the genetic code (Frappat L., Sciarrino A. and Sorba P., Phys. Lett. A, 250 (1998) 214).
