Information Question Use the following information to answer Questions 5 through 9. You are a forensic scientist and you are able to obtain the following 3 CODIS STR genotypes from an evidence sample found at a crime scene: Locus Evidence Genotype TH01 5,5 TPOX 16,17 vWA 10,11 A reference sample from a suspect has the same exact genotypes as the evidence sample. Using the database table of genotypes below and the genotypes of the evidence sample, answer the following questions. Calculate the probability that the genotypes from the evidence sample found at the crime scene and the reference sample from the suspect are from 2 different individuals but coincidentally matched by chance. Individual THO1 TPOX vWA 1 5,5 16,16 10,10 2 3,7 16,17 10,12 3 3,4 16,15 13,14 4 5,5 14,17 11,12 5 4,4 17,17 11,11 6 4,8 17,17 10,10 7 7,8 19,19 10,12 8 9,9 18,19 14,14 9 3,6 15,15 13,14 10 8,9 19,20 11,11 What is the frequency of allele 5 for the TH01 locus?
