Figure 3From: A BAC-based physical map of the Nile tilapia genomeQ scores for contigs of different size. The number of questionable clones identified by FPC rises with the size of the contig. Very large contigs tend to have a disproportionate number of Q's, suggesting improper assembly of repetitive sequences. The line represents a least squares fit of y = 0.252x (r2 = 0.54).Back to article page
