This paper analyses the compositional correlations that hold in the chicken genome. Significant linear correlations were found among the regions studied—coding sequences (and their first, second, and third codon positions), flanking regions (5′ and 3′), and introns—as is the case in the human genome. We found that these compositional correlations are not limited to global GC levels but even extend to individual bases. Furthermore, an analysis of 1037 coding sequences has confirmed a correlation among GC3, GC2, and GC1. The implications of these results are discussed.
