Suppose that a crime scene DNA sample was recovered and a suspect was later arrested. The DNA profiles of the crime strain and the suspect were typed and poth had the same DNA profiles at loci THO1, TPOX and CSF1PO. If both had alleles 7 and 9 for THO1, alleles 11 and 12 for TPOX, and allele 12 for CSF1P0, compute the match probability and likelihood ratio using the chart below. State the likelihood ratio in words.

Transcribed Image Text:The match probability rounded to six decimal places is:
The Likelihood Ratio as a whole number (using the rounded number above in the equation) is:
Which is the correct definition of the likelihood ratio?
O A. There is a 1 in LR chance that a random person is the criminal.
O B. There is a 1 in LR chance that the blood of a random person matches the blood at the crime scene at the loci THO1, TPOX, and CSF1PO.
O C. There is a 1 in LR chance that the suspect is guilty.
O D. There is a 1 in LR chance that the blood of the suspect matches the blood at the crime scene at the loci THO1, TPOX, and CSF1PO.
