  1. Values reported for ENC, Fop, GC total, and GC3 are means for all genes from D. melanogaster and D. yakuba combined (95% confidence interval). Values for gene length are the mean number of base pairs in D. melanogaster for all constitutively spliced exons concatenated, for each gene (95% confidence interval). The no crossing over region is divided as follows: NO, non-fourth chromosome genes; N4, fourth chromosome genes; and NA, all no crossing over region genes. ENC, effective number of codons; Fop, frequency of optimal codons; GC3, GC content of the third position of codons.
