Figure 4.

Relative distribution of rDNA sites along the chromosome arm in 397 angiosperm (+) and 38 gymnosperm (o) karyotypes. The distance from the site to the centromere was represented as a percentage value in relation to the centromere-telomere length of the arm bearing the rDNA site. Whole arm (wa) sites were not included in this sample.
