Question 5:

Solving the Case with Genetic Evidence

Objective: Use your understanding of genetics to analyze a fictional forensic scenario involving DNA evidence and determine the likely suspect.

Scenario:

A crime has taken place in a small town, and investigators have collected DNA samples from three potential suspects and a blood sample found at the crime scene. The DNA profile from the blood sample shows the following alleles at three specific loci:

  • Locus 1: A/A
  • Locus 2: B/C
  • Locus 3: D/D

The DNA profiles of the suspects are as follows:

  • Suspect 1:
    • Locus 1: A/A
    • Locus 2: B/B
    • Locus 3: D/D
  • Suspect 2:
    • Locus 1: A/C
    • Locus 2: B/C
    • Locus 3: D/E
  • Suspect 3:
    • Locus 1: A/A
    • Locus 2: C/C
    • Locus 3: D/D

Questions:

  1. DNA Match Analysis:
    • Based on the DNA profiles, which suspect(s) could potentially match the DNA found at the crime scene? Explain your reasoning by comparing the alleles at each locus.
  2. Genetic Evidence in Court:
    • Consider the role of DNA evidence in the criminal justice system. What are the strengths and limitations of using genetic information to establish guilt or innocence in a forensic investigation?
  3. Written Submission:
    • Your response should be 200-300 words, addressing the questions above with clear explanations and logical reasoning.

Grading

Remember to assign yourself a grade!

  • Please remember that hard work doesn't equal high performance or good grades. Your work should reflect that.

If there's a discrepancy between your grade and mine, I'll provide comments explaining why the grade differs. If you think you're doing great in the real world, but the numbers and evaluations suggest otherwise, you should step up or explore alternatives. This assignment helps you gauge your actual performance and self-reflection skills.
