If you are searching for the , you are likely either a teacher verifying results, a student checking your work, or a curriculum developer updating your resources. The "UPD" (Updated) tag is critical here—genetics standards and blood typing compatibility rules have nuance, and answer keys from 2015 often contain oversimplifications.
: The Grandfather has Type AB blood, meaning his genotype is strictly IAIBcap I to the cap A-th power cap I to the cap B-th power
To solve the pedigree, you must work backward from the children's blood types to find the father's (Joseph) missing information: : Joseph has : His genotype is cap I to the cap B-th power i for blood type and (heterozygous) for the Rh factor. : Since Joseph and Rita (who is cap I to the cap A-th power cap I to the cap B-th power lab activity blood type pedigree mystery answer key upd
The Blood Type Pedigree Mystery challenges students to apply Mendelian and non-Mendelian genetics to a real-world scenario (such as a hospital baby mix-up or a forensic inheritance dispute). By completing this lab, students will:
| Evidence Component | Finding | Implication | | :--- | :--- | :--- | | | Type A- | Suspect must have genetic ability to have Type A blood | | Witness testimony | Attached earlobes | Suspect must have ee genotype | | Suspect III-4 | Type A & attached | Matches both pieces of evidence ✅ | | Other suspects | Other blood types or free earlobes | Do not match all evidence ❌ | | Motive | Not a blood relative | Ineligible for inheritance → jealousy | If you are searching for the , you
The Grandparents: Usually, one is Type O (OO) and the other is Type A or B, establishing the presence of the recessive allele in the first generation.The "Mystery" Child: Often, students must determine if a child could belong to a specific set of parents. If the parents are Type AB and Type O, the child can only be Type A (AO) or Type B (BO). If the lab asks why a Type O child doesn't fit, the answer is that the AB parent lacks the recessive allele.The Missing Genotypes: For Type A or B individuals with one Type O parent, the answer key will always list them as heterozygous (AO or BO). Why This Lab Matters
Most educational databases (Teachers Pay Teachers, Ward's Science, or BioCorner) have refreshed their "Blood Type Pedigree Mystery" files in 2024-2025. Search for version "UPD 2.0" which includes the corrections noted above. : Since Joseph and Rita (who is cap
Because Family 1 parents are both IAicap I to the cap A-th power i , they can produce an (Type O) child ( from mother + from father). Baby 2 (Type AB) belongs to Family 2. Because Mrs. Jones is ABcap A cap B IAIBcap I to the cap A-th power cap I to the cap B-th power ), she can pass on either an allele, making it possible to have an ABcap A cap B V. Final Answers (Answer Key) Which baby belongs to the Smith Family? Answer: Baby 1 (Type O) Reasoning: IAicap I to the cap A-th power i IAicap I to the cap A-th power i can produce an (Type O) child. Which baby belongs to the Jones Family? Answer: Baby 2 (Type AB) Reasoning: Mrs. Jones ( IAIBcap I to the cap A-th power cap I to the cap B-th power ) can produce an AB child, whereas the Smiths cannot. Pedigree Diagram Explanation:
