In a PCR-based crime scene investigation, similar to the one presented in the lab module with Brother Y and Brother X, there is a sample of DNA from a crime scene that is likely to belong to the guilty party. Based on the gel photo below, which shows the results of an electrophoresis gel following PCR amplification at one locus of 5 DNA samples - one crime scene sample and 4 suspects - which suspects can be excluded from this investigation? [Keep in mind that it is not possible for a  heterozygous person to leave only one allele at a crime scene. If any one allele does not match, then that suspect is eliminated.] choose all that apply

Crime Scene Investigation

A crime scene refers to a place where a crime has occurred. The purpose of crime scene investigation (CSI) is to analyze the complete scene and catch the culprit based on the pieces of evidence collected from the place of crime. The people involved in this process are referred to as crime scene investigators.
