In RAPDs the DNA components are separated within a gel and patterns in band presence (see arrow) indicate genetic relatedness (Photo: Deborah Hofstra).
Quillworts from lakes of different regions show geographic patterns of relatedness based on the RAPDs method of genetic analyses. More genetically similar populations occur on shorter 'branches'.
