Figure 1From: Characterisation of a transcriptome to find sequence differences between two differentially migrating subspecies of the willow warbler Phylloscopus trochilusFrequency distribution of distances to the closest gene feature for 32,351,947 aligned positions in intergenic regions of the zebra finch genome. Excluded are 4,912,443 positions located on chromosomes with unplaced contigs (e.g. chr3_random and chrUn).Back to article page
