Lab Activity Blood Type Pedigree Mystery Answer Key Upd 2021 | FRESH |

Students must analyze the three-generation family pedigree to determine if Leo is biologically related, identify genotypes for all family members, and solve the "mystery" of the missing alleles. 3. Master Answer Key & Pedigree Solutions Generation I (Grandparents) Genotype must be IAicap I to the cap A-th power i . Proof: He had a child (Charles) with Type O blood ( ). Charles had to inherit a recessive allele from both parents.

Determine the genotypes for blood type of Joseph and his family members. Since you don't know Joseph's genotype, you will need to.

Unlike simple Mendelian traits that have two alleles (e.g., tall vs. short), blood type is determined by : lab activity blood type pedigree mystery answer key upd

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

Ensure pedigrees use circles for females and squares for males. Proof: He had a child (Charles) with Type O blood ( )

Students must first translate phenotypes into workable genetic combinations. The Allele Key IAcap I to the cap A-th power : Allele for Type A (Dominant) IBcap I to the cap B-th power : Allele for Type B (Dominant) : Allele for Type O (Recessively inherited) Master Genotype Answer Key Family Member Phenotype (Blood Type) Confirmed Genotype Grandfather IAIBcap I to the cap A-th power cap I to the cap B-th power Grandmother Father (Arthur) IAicap I to the cap A-th power i Mother (Eleanor) IBicap I to the cap B-th power i Daughter (Alice) Claimant (Charles) IAIBcap I to the cap A-th power cap I to the cap B-th power Part 2: Step-by-Step Pedigree Analysis 1. Proving Arthur's Genotype Grandfather passes either IAcap I to the cap A-th power IBcap I to the cap B-th power to his children. Grandmother can only pass the recessive allele Arthur has Type A blood, so he received IAcap I to the cap A-th power from his father. Arthur received from his mother. IAicap I to the cap A-th power i 2. Proving Eleanor's Genotype Alice has Type O blood, meaning her genotype is Alice must inherit one allele from each parent. Arthur provides one recessive Eleanor has Type B blood but must carry the hidden Eleanor's Genotype: IBicap I to the cap B-th power i Part 3: Punnett Square Verification Students must cross Arthur ( IAicap I to the cap A-th power i ) and Eleanor ( IBicap I to the cap B-th power i ) to find possible offspring.

The most common version of this activity is the "Mystery in Wexford." Here's the scenario: Since you don't know Joseph's genotype, you will need to

Genotype appears to be .

Type AB parents can only produce AB, A, or B offspring; they can never produce an O child.
