We already determined the Jones family cannot have an AB child.

To find the total probability of the Father and Mother having a child who is , multiply the individual probabilities:

Any relative with Type B, Type AB, or Type O blood is excluded if the evidence is Type A. Final Identification:

The ABO blood type in humans is determined by a single gene (the I gene) that comes in three different versions (alleles): lab activity blood type pedigree mystery answer key upd

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.

In a typical blood type pedigree, we assume that every person inherits one allele for a gene from each parent. UPD can break this rule in two main ways:

Unlocking the secrets of genetics often involves solving complex puzzles. One popular, engaging classroom lab is the (also known as the "Mystery in Wexford"). In this activity, students act as genetic detectives to analyze a family tree, determine genotypes, and identify a thief.

A prominent family, the Harringtons, discovers a medical anomaly during a routine wellness check. The youngest child, Leo, is rushed to the hospital and requires a blood transfusion. When the family members are tested for compatibility, a startling revelation surfaces: Leo's blood type does not seamlessly align with what the parents expected based on a basic understanding of inheritance.

The "+" or "-" in a blood type (like A- or B+) refers to the Rh factor, another inherited trait. It is typically treated as a simple dominant/recessive trait where is dominant over negative (Rh-) .

Follows codominance (A and B are both expressed) and multiple alleles (A, B, and O).

) in generation 3, both parents in generation 2 MUST carry the allele, even if they are Phenotype A or B. 3. Key Genetics Concepts Used To get the right answer, you must master these concepts: The ABO gene has three alleles: Codominance: IAcap I to the cap A-th power IBcap I to the cap B-th power are codominant. If you have both, you are Type AB. Recessive: is recessive. You need to be Type O. Genotype vs. Phenotype: Type A can be 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
