Blood Type Pedigree Mystery lab activity, the thief is identified as . Based on the clues provided in the scenario, has blood type attached earlobes , matching the evidence collected at the crime scene. Course Hero 1. Identify inheritance patterns

(homozygous A), not IAi. Update the answer. lab activity blood type pedigree mystery answer key upd

While specific family data can vary, the core logic remains the same. Below is a generalized example that illustrates how to solve the mystery using a hypothetical family's data.

Step 2: Identify the CodominantsNext, locate the Type AB individuals. Their genotype is always AB. These individuals are "fixed points" in your puzzle because there is no ambiguity about which alleles they carry.

Wealthy elderly Joseph dies, and a sum of money is stolen from his safe. Fresh blood and a specific physical trait (attached earlobes) are found at the scene. The Objective: ), leaving Baby Y as an impossibility for

Other Offspring Must match parent/grandparent alleles. 3. The Thief Identification (Most Common Solution)

Create a family pedigree to determine genotypes and identify which relative (the thief) matches the evidence. Answer Key & Data Summary The evidence points to

for other types of inheritance (e.g., Cystic Fibrosis). Which area
