While the patterns of coverage seem to indicate a notable bias in the per-site distribution of the coverage depth across coding genes for the SOLiD data, a moderate, but highly significant ( r = 0.25, P < 0.0001) correlation was observed between per base coverage by SOLiD and Solexa/Illumina sequencing for individual positions in the coding sequences of the 37 genes of mitochondrial ancestry—possibly due to a known dependence of recovery of fragmented cDNA (by gel elution) on GC content ( 35 ).
