Lab Activity Blood Type Pedigree Mystery Answer Key Upd | Premium

The Rh factor is inherited independently of the ABO blood type. It follows simple Mendelian dominant/recessive inheritance rules based on the presence or absence of the D antigen: : Codified by the dominant allele ( ). Genotypes can be RRcap R cap R Rh-Negative ( Rh−cap R h raised to the negative power ) : Codified by the recessive allele ( ). The genotype is always Part 2: Step-by-Step Pedigree Analysis Strategy

Medical records of the family's blood types have been recovered. Students must reconstruct the pedigree chart, fill in the missing genotypes, and determine if Charles is genetically linked to the family. The Recovered Medical Data Arthur Pendelton (Grandfather - Deceased): Type AB Eleanor Pendelton (Grandmother): Type O Generation II (Children & Spouses): Beatrice (Arthur & Eleanor's Daughter - Deceased): Type A Edward (Beatrice’s Husband): Type B David (Arthur & Eleanor's Son): Type B Grace (David’s Wife): Type A Generation III (Grandchildren):

This comprehensive guide walks you through the entire lab, from the initial crime scene to the final deduction. We'll demystify the genetics involved, provide a detailed step-by-step solution guide, and even offer a completed answer key to support educators or help students check their understanding. lab activity blood type pedigree mystery answer key upd

as a daughter of Joseph and Rita. In many versions of this mystery, Jane's Type O blood reveals she is either adopted or provides the key that Joseph must carry an is A+: Since Rita is Rh- ( ), the Rh+ allele ( ) must come from Joseph. Joseph is Type B+ with the genotype . 2. Identifying the Inheritance Patterns The lab tracks two distinct genetic traits:

In the context of a high school biology lab, UPD is an interesting footnote—a reminder that the simple rules of inheritance have rare and fascinating exceptions.

), there may be a biological "mystery" or adoption, as an AB parent cannot typically have an O child.

Create a pedigree for a fictional family with a mystery trait. Use genetic principles to determine the genotypes and phenotypes of each family member. Share your pedigree with the class and see if they can solve the mystery! The Rh factor is inherited independently of the

Based on these rules, here are the possible genotypes and their corresponding phenotypes (blood types):

Here are the answers to the key analytical questions that accompany the lab:

: Identifying the thief (common suspects include family members like Danny or Shayna) and justifying the choice with Punnett squares and motive analysis . Common Answer Key Points

The key to the mystery is identifying the genotypes of family members based on their blood types (phenotype). Means both parents must carry a lowercase Type AB ( IAIBcap I to the cap A-th power cap I to the cap B-th power ): Means the child must have received IAcap I to the cap A-th power from one parent and IBcap I to the cap B-th power from the other. Individual Joseph IBicap I to the cap B-th power i IBIBcap I to the cap B-th power cap I to the cap B-th power IBcap I to the cap B-th power Rita IAicap I to the cap A-th power i IAIAcap I to the cap A-th power cap I to the cap A-th power IAcap I to the cap A-th power Danny IAicap I to the cap A-th power i Often the key suspect due to heterozygous genotype.

Construct the Family Pedigree

John has blood type A, which means his genotype can be either AA or AO. Since Mary has blood type O, her genotype must be OO.
