). Her blood type is and she has attached earlobes , which matches the evidence found at the scene. Joseph’s blood type is determined to be B+ with the genotype BOcap B cap O . 1. Determining Joseph’s Genotype

Students must evaluate which child belongs to which set of parents based on genetic possibility. 1. The Davis Family Investigation : Mr. Davis (Type AB+) Mrs. Susan Davis (Type O-) Parental Genotypes : IAIBcap I to the cap A-th power cap I to the cap B-th power (Rh status unknown/heterozygous Possible Offspring Genotypes : IAicap I to the cap A-th power i (Type A) or IBicap I to the cap B-th power i lab activity blood type pedigree mystery answer key upd

He can legally and biologically be the grandson of Generation I. The pedigree yields no genetic mismatches or evolutionary impossibilities. Part 2: Punnett Square Proofs & Mathematical Probabilities

Have you ever wondered how blood type is inherited? Or how to determine an individual's blood type based on their family history? In this lab activity, we will explore the fascinating world of blood type genetics and solve a pedigree mystery.

Rh system basics

In this lab activity, we solved a pedigree mystery by applying our knowledge of blood type genetics. We determined the genotypes of each family member and uncovered the unexpected inheritance of a B allele in John. This activity demonstrates the importance of understanding genetic principles to analyze and predict the inheritance of traits.

allele . He cannot have a biological child with Type O blood ( However, two Rh-negative parents ( ) can never

Phenotype is Type O , meaning his genotype is . The Genotypic Math: Charles requires one allele from Beatrice and one allele from Edward. We know Beatrice is IAicap I to the cap A-th power i (she can provide an Edward is Type B . If Edward's genotype is IBicap I to the cap B-th power i , they can successfully produce a Type O child ( The Punnett Square (Beatrice IAicap I to the cap A-th power i IBicap I to the cap B-th power i ): IBcap I to the cap B-th power IAcap I to the cap A-th power IAIBcap I to the cap A-th power cap I to the cap B-th power IAicap I to the cap A-th power i IBicap I to the cap B-th power i (Type O)
