Gaps in comparative-grade finished BAC sequences from multiple genomic regions. The comparative-grade finished sequences of the 2,031 BACs summarized in Tables 2 and 3 were analyzed for the presence of uncaptured (orange bar) and captured (blue bar) gaps (see text for details). The numbers of captured and uncaptured gaps per Mb averaged across all BACs from each indicated genomic region (A) or species (B) are indicated. Each error bar represents the 95% confidence interval. In A, the data for three additional ENCODE pilot project regions (ENr231, ENr232, and ENr333) are shown for comparison because of the notably high frequency of gaps in their sequences; however, there were not sufficient numbers of sequenced BACs from these regions to qualify for inclusion in the second data set (see text for details).
