Suppose that 500 bp of nucleotide sequence information (representing the same genomic DNA location) was compared between DNAs obtained from three different sources: 1) crime scene DNA, 2) DNA from suspect 1, and 3) DNA from suspect 2. It was found that none of the sequences were identical to one another. The crime scene DNA differed from that of suspect 1 at one location (499 nucleotides were identical), and differed from that of suspect 2 at two different locations (498 nucleotides were identical). What should be the conclusion

1. seamount a raised footwall block between normal fault creates this 2. syncline break between rocks where a hanging wall rises relative to a footwall 3. hot spring on rolling hills, this a dip between hills 4. volcanic neck created when a block with hanging walls slips down between normal faults 5. caldera underwater volcano that never reaches above sea level 6. horst natural hot water on earth's surface containing many minerals 7. graben underwater volcano whose top is eroded flat by waves 8. crater less than a mile in diameter; looks like a bowl at the top of a volcano 9. guyot magma that filled the central vent that remains after the volcano has eroded 10. reverse fault over 1 mile in diameter; looks like a bowl over a volcano
