Lab Activity Blood Type Pedigree Mystery !exclusive!

The lab typically presents the following evidence found at the crime scene:

The primary goal of this activity is to help students move beyond simple Punnett squares and into the application of and codominance . While most traits are taught as simple dominant or recessive, the ABO blood system provides a real-world example where: A and B are codominant (forming the AB blood type). O is recessive to both A and B. lab activity blood type pedigree mystery

Therefore, the hypothesis that Claimant X is the biological offspring is as plausible. However, it is important to note that blood typing can only exclude paternity; it cannot confirm it with the certainty of DNA fingerprinting. This lab successfully demonstrated the predictive power of Punnett squares and the importance of understanding dominant, recessive, and codominant inheritance patterns in solving real-world biological problems. The lab typically presents the following evidence found
