Because she has Rh- blood, her Rh genotype must be . Her ABO genotype could be IBIBcap I to the cap B-th power cap I to the cap B-th power IBicap I to the cap B-th power i Mr. Smith (A+): His Rh genotype could be . His ABO genotype could be IAIAcap I to the cap A-th power cap I to the cap A-th power IAicap I to the cap A-th power i Mrs. Jones (O+): Her ABO genotype must be . Her Rh genotype could be Mr. Jones (AB+): His ABO genotype must be IAIBcap I to the cap A-th power cap I to the cap B-th power . His Rh genotype could be Part 2: Pedigree Analysis & Punnett Squares Analyzing the Jones Family Options ABO Options: Mr. Jones ( IAIBcap I to the cap A-th power cap I to the cap B-th power ) x Mrs. Jones ( can only produce offspring with genotypes IAicap I to the cap A-th power i (Type A) or IBicap I to the cap B-th power i

Proof: Phenotypically Type O individuals can only possess the homozygous recessive genotype. Genotype is IAIBcap I to the cap A-th power cap I to the cap B-th power . Proof: Phenotypically Type AB requires one IAcap I to the cap A-th power allele and one IBcap I to the cap B-th power Edward Harrington (Uncle - Type B): Genotype is IBicap I to the cap B-th power i . Proof: He inherited the IBcap I to the cap B-th power

Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population. Key Concepts Reinforced Multiple Alleles: The IAcap I to the cap A-th power IBcap I to the cap B-th power Codominance: IAcap I to the cap A-th power IBcap I to the cap B-th power are expressed equally in type AB blood. Complete Dominance: Both IAcap I to the cap A-th power IBcap I to the cap B-th power completely mask the recessive allele (Type O). Quick Reference: Blood Type Genetics

Joseph and Rita, a wealthy elderly couple in Wexford, have a complicated family history. Following Joseph’s tragic death, a significant sum of money goes missing. Students must use blood types and physical traits (like earlobes) to track down the thief among family members. Learning Objectives Construct a family pedigree chart using proper symbols. Determine Genotypes ( IAIAcap I to the cap A-th power cap I to the cap A-th power IAicap I to the cap A-th power i IBIBcap I to the cap B-th power cap I to the cap B-th power IBicap I to the cap B-th power i IAIBcap I to the cap A-th power cap I to the cap B-th power ) for blood types. Analyze Pedigrees to track inheritance patterns. Defend Conclusions using evidence and Punnett Squares. 🔑 Lab Activity Blood Type Pedigree Mystery Answer Key

In the sterile glow of the Neo-Gene Lab, Dr. Aris Thorne stared at the digital pedigree chart glowing on his tablet. The family tree belonged to the Montgomerys, a lineage of old wealth, but it was currently telling a story of biological impossibility. lab activity blood type pedigree mystery answer key upd

) . You don't have to guess if they are homozygous or heterozygous. What are the "Red Flags" for a thief?

Blood Type Pedigree Mystery is a popular genetics lab where students use ABO blood groups and secondary traits (like earlobe attachment) to solve a theft at the "Wexford" estate. Mystery Overview The Scenario:

The key clues were the O child (both parents must carry i) and the AB child (parents provide IA and IB), plus Rh− children requiring both parents to carry d. Combining ABO and Rh inheritance pinpoints the mystery individual as genotype IAi, dd (phenotype A−).

Look for the reasoning: Students should explicitly state that Mr. Jones cannot pass on an Because she has Rh- blood, her Rh genotype must be

The Rh factor (+ or -) is inherited via simple complete dominance. The positive allele ( ) is dominant over the negative allele (

If you are a teacher, you want students to discover the answer, not copy it. Here is a scaffolding strategy using this key:

Your mission is to create a pedigree (a family tree) for Joseph and Rita's family, map out the blood types and earlobe traits for all potential suspects, and use genetic principles to identify the culprit.

Is there a included in your lab (e.g., a crime scene, a missing heir, or a hospital mix-up)?

Yes. If both parents are heterozygous for the trait (genotype IAicap I to the cap A-th power i

The "Blood Type Pedigree Mystery" lab activity is a classic high school biology exercise. It blends concepts of genetics, multiple alleles, codominance, and pedigree analysis. Students solve a realistic mystery—such as a hospital baby mix-up or a disputed inheritance—using blood type phenotypes to determine genotypes and family relationships.
