Duplications, gene density, and free energy for genes anchored to genomic locations. a Evidence of gene duplications in the gene annotation at two E-value thresholds: 1 × 10−20 and 1 × 10−50 (light and dark orange, respectively). b Frequency distributions of 3049 randomly selected protein coding genes using a weighted sampling schema binned into 1 Mbp bins. c Long non-coding RNA frequency of all lncRNAs that aligned to the reference genome binned into 1Mbp bins. d Raw (uncorrected) free energy values for 3049 lncRNAs that aligned to the reference genome (purple) and 3049 randomly selected protein coding genes (orange) (p < 2.2 × 10−16)
