Summary Introduction

To determine: Whether the combined frequency of the alleles point to the suspect as a perpetrator

Introduction: DNA profiling has been used in criminal and civil investigations. The allele frequency with a number of STR probes is calculated, and the probability is matched with the suspect.

c.

Summary Introduction

To determine: The additional data that can be obtained from the DNA lab to find the perpetrator.

Introduction: The use of DNA profiling has brought about a major revolution in criminal and civil proceedings. The DNA is probed with four STR allele probes, and the frequency is calculated to determine or identify the perpetrator.

d.

Summary Introduction

To determine: Whether jurors in judicial system understand basic probability and whether DNA evidence can mislead jurors to make a false decision.

Introduction: DNA was first used as forensic evidence in 1986 since then DNA profiling has brought about a major revolution in criminal and civil proceedings. The analysis of DNA profiling includes the study of probability, statistics and population genetics.

Students have asked these similar questions

Police discovered the body of a woman who had been brutally assaulted. DNA from the crime scene was analysed and yielded the following SNP genotype: A1A2, G2G2, T1T2 for both the victim and a suspect. If the frequencies of A1, G1 and T1 alleles are 0.9, 0.99, 0.8 respectively, calculate the probability that another person in the group of suspects is responsible for the crime.

An important application of DNA fingerprinting is relationship testing. Persons who are related genetically have some bands or peaks in common. The number they share depends on the closeness of their genetic relationship. For example, an offspring is expected to receive half of his or her minisatellites from one parent and the rest from the other. The diagram shown here schematically illustrates traditional DNA fingerprints of an offspring, mother, and two potential fathers. In paternity testing, the offspring’s DNA fingerprint is first compared with that of the mother. The bands that the offspring have in common with the mother are depicted in purple. The bands that are not similar between the offspring and the mother must have been inherited from the father. These bands are depicted in red. Which male could be the father?

Someone broke into the bookstore and stole thousands of dollars’ worth of textbooks. Some hairs were left behind, from which DNA was extracted. An individual was caught with all five of the stolen textbooks in his bag. He claims his friend gave them to him. You decide to amplify two regions of the DNA (two loci, plural of locus) and digest the samples, and get the following result on the electrophoresis gel.L = Standard marker 1 = Suspect 1 2 = Suspect 2 3 = DNA from crime scene (Note: assume bands that are close in distance traveled are the same length. Higher concentrations of DNA can make a band appear to travel farther.) Who is most likely the culprit, and how do you know?
