Question

You are a member of the jury for a murder case. the prosecution has presented dna evidence linking the defendant to the crime scene. the defense claims that dna evidence using str analysis with 13 markers is not sufficient to reliably distinguish between people. what do you think?

Answer 1

Actually they are right. STR analysis with 13 markers gives a 1 in 10 billion or greater chance that two people will have the same pattern. So we can conclude that he was in the crime scene. STR analysis with 13 markers should be sufficient to distinguish between any two people on the planet.
