The crime scene evidence includes a blood smear (Type A-) and the thief's trait of attached earlobes.
They have the specific recessive trait (attached earlobes) seen by the witness.

If you need help adjusting this key for a of the pedigree mystery lab or want me to draft a corresponding student worksheet , let me know! Please tell me: Do your materials include the Rh factor (+/-)?
They allow for predicting the probability of inheritance in future generations. 🚀 How to Proceed
Before diving into the pedigree analysis, students must master the unique inheritance pattern of human blood types (the ABO system). The ABO Blood System Human blood groups are determined by three alleles: IAcap I to the cap A-th power IBcap I to the cap B-th power . This system demonstrates two distinct genetic phenomena: Alleles IAcap I to the cap A-th power IBcap I to the cap B-th power : The crime scene evidence includes a blood
According to the Punnett Square above, the biological children of a Type A (Heterozygous) father and a Type O mother can only be:
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
Before grading or delivering the lab, review the standard phenotypes and genotypes utilized in the pedigree chart: Phenotype (Blood Type) Genotype(s) Antigens on Red Blood Cells 🔬 Lab Overview: The Case of the Missing
Unlike simple Mendelian traits that have two alleles (e.g., tall vs. short), blood type is determined by :
She possessed the incredibly rare Bombay phenotype. Because she lacked the ability to produce the H-antigen—the chemical base required to make A or B antigens attach to red blood cells—her blood tests always defaulted to type O. She was a genetic chameleon. She carried the functional B gene, but it was masked, hidden in plain sight for her entire life.
