Figure 5From: Some novel intron positions in conserved Drosophila genes are caused by intron sliding or tandem duplicationRelative locations of novel introns supported by NIPs. Reference for the determination of the intron position within the genes is D. melanogaster. The CDS were split into 10 bins of equal size. The numbers of TD introns (blue) and apomorphic ON introns (yellow) were counted. Compared to a uniform distribution both classes together show a 5' bias (p = 0.035; one-sided, binomial test).Back to article page
