DNA fingerprinting in clonal organisms



The use of DNA fingerprinting to identify members of the same clone in completely or partially asexual organisms requires that the individuals within a clone share a recent common ancestor. By considering the expected distributions of band–sharing values in asexual and sexual organisms, it is shown that DNA fingerprinting may be effective in distinguishing members of the same clone, provided that the frequency of sexual reproduction is considerably greater than the minisatellite mutation rate.
