Two probes, A and B, hybridize very near each other in a region of DNA that contains RFLPs when digested with HindIII. The four maps show the location and intervening distances of the HindIII restriction sites and the binding locations of probes A and B. The maps show alleles H1-H4 present in a population. What band(s) is/are seen in Southern blot analysis of a H2H3 heterozygote using probe B?
