Based on these rules, here are the possible genotypes and their corresponding phenotypes (blood types):
Proof: Phenotypically Type O individuals can only possess the homozygous recessive genotype. Genotype is IAIBcap I to the cap A-th power cap I to the cap B-th power . Proof: Phenotypically Type AB requires one IAcap I to the cap A-th power allele and one IBcap I to the cap B-th power Edward Harrington (Uncle - Type B): Genotype is IBicap I to the cap B-th power i . Proof: He inherited the IBcap I to the cap B-th power

: A wealthy man named Joseph dies, and a sum of money is stolen from his safe. A blood smear (Type A-) is found at the scene, and a witness notes the thief has attached earlobes . Based on these rules, here are the possible
To solve the mystery, students must first understand the genetic rules governing blood types. Unlike simple dominant-recessive traits, the ABO system involves and codominance . Genetics of blood type: inheritance and compatibility
, etc.). Individuals with attached earlobes should be represented by shaded symbols to indicate the recessive phenotype. Coventry Local Schools Final Answer: The thief of the Wexford estate money is Proof: He inherited the IBcap I to the
The Rh factor (+ or -) follows simple Mendelian inheritance. The positive allele ( ) is completely dominant over the negative allele ( −negative Phenotype to Genotype Mapping: Type A: IAIAcap I to the cap A-th power cap I to the cap A-th power (Homozygous) or IAicap I to the cap A-th power i (Heterozygous) Type B: IBIBcap I to the cap B-th power cap I to the cap B-th power (Homozygous) or IBicap I to the cap B-th power i (Heterozygous) Type AB: IAIBcap I to the cap A-th power cap I to the cap B-th power (Codominant) Type O: (Recessive) Rh+: ++positive positive +−positive negative Rh-: −−negative negative The Mystery Scenario (Standard Setup)
If Baby X is Type O- and Baby Y is AB-, and the families are Smith ( ) and Jones ( The Smiths can have any blood type (A, B, AB, or O). The Joneses can only have Type A or Type B.
A wealthy patriarch (The Grandfather) has passed away, leaving a significant inheritance. A young individual (The Claimant) steps forward, claiming to be the long-lost grandchild and heir. The family disputes this claim. Students are provided with the blood types of the grandparents, the parents, and the claimant. The objective is to determine if the claimant could biologically belong to this family tree.
