I already know that the corretc answer for number one is A) suspect 1 because his DNA sampe matches with the evidence sample, but I need help with number 2. Thanks!

The Case of Druid Dracula Peggy Brickman, University of Georgia Modified by Dr. T. Greene VCU Biology Part III The Report (Homework) The crime was featured on BBC\'s Crimewatch program in December 2001 and North II aa Wales Police received over 200 calls. Following reports of a teenager who had attacked a l EE German student, the police went to the home of Matthew Hardman (suspect 1), who gave i H ii police a cheek swab. During this visit, officers found a pair of Levi shoes. Forensic Science Service (FSS) scientists matched Hardman\'s shoes to the footwear marks found ii at the murder scene. Profiling suggested a much older offender, so another suspect was EE also asked to give a cheek swab (suspect 2). Since both suspects were men, the officers s needed to for other genetic differences. They focused on STRs (short repeats), stretches of DNA that exist in all people, but in different numbers of repeats. E L:: a Lae EE ee Below is the STRs on chromosome 11 for both suspects and regions on other chromosomes as shown by karyotype on the right. 11 of suspect same pair in suspect 2: 1. Which suspect presents a profile compatible to the sample found at the crime scene? a. Suspect 1 b. Suspect #2 Allele lakler Awitive Control 2. What information/s led to your conclusion in (1)? Give two pieces of evidence from the DNA Negative Control profile to support your answer. Evidence Sample Suspect I Reference Suspect Ref

Solution

1. A

Suspect 1 STR profile matches perfectly with the evidence sample so probably suspect 1 was involved in the crime.

2. Just compare the green peaks it the suspect 1 STR peaks matches perfectly with the crime evidence. Especially focus on green peak 3,4,5,6,7 of evidence peaks to suspects this is perfectly matching with the suspect 1.
