Figure 4. Polymorphic rcPtERVs in chimpanzee individuals.

Figure 4

Two of eight potential rcPtERV loci were polymorphic and the PCR results are shown in this figure. In the strategy for PCR amplification, the colored arrows indicate the positions of PCR primers; the red and blue arrows indicate forward and reverse flanking primers, respectively. Green and yellow arrows indicate reverse and forward internal primers which are specific to PtERV elements. PCR band in the upper gel picture indicates the absence of the rcPtERV while PCR band in the middle and bottom gel picture indicates the presence of the rcPtERV.
