Question

Please answer questions 7-9 and fill out the table (UV-13, A and B)

**B: ABO Frequencies**

The ABO Blood Group System is an example of a genetic cocominant trait that exhibits three alleles: \(i^A\), \(i^B\), and \(i\), and four phenotypic characteristics. Dominance and codominance among these alleles are essential to understand the genetic expressions for these traits. We will use the Hardy-Weinberg Equations for three alleles:

1. What is the dominant phenotypic trait? ___
2. What is the codominant phenotypic trait? ___
3. What is the possible genotype for this trait? ___
4. What is the recessive phenotypic trait? ___
5. What are the other possible phenotypic traits? ___
6. What are the other possible genotypes for these traits? ___

Using these questions, you'll fill in Table UV:13 with the allele and genotype frequencies and population estimates for the \(i^A\) and \(i^B\) antigens. The calculations are based on the Hardy-Weinberg Equation and formula.

**Tables Explanation**

_Table UV:13_

**A) Allele and B) Genotype Frequencies**

- **A) Alleles and Frequencies**

  - Lists alleles \(i^A\), \(i^B\), and \(i\)
  - Dominance is annotated for each allele
  - Frequency notations (e.g., \(p\), \(q\), \(r\))

- **B) Genotype and Population Estimates**

  - Genotype pattern examples: \(i^Ai^A\), \(i^Ai\), \(i^Bi^B\), \(i^Bi\), \(ii\) 
  - Includes phenotype trait, genotype frequencies, and population estimates

The table serves to visualize the genetic makeup distribution within a population based on the Hardy-Weinberg principles, allowing students to analyze how alleles combine and manifest as phenotypes. Calculating these values helps in understanding population genetics dynamics for ABO blood types.

**Instructions:**

10. Calculate the allele and genotype frequencies for the \(i^A\) and \(i^B\) antigens in the Bio 3302L population and show these calculations in the space provided.

**Part 5: Calculating Frequencies**

Over several semesters, a population of 251 students from the Anatomy and Physiology II Laboratory typed their blood. In this lab, we will use their results to predict the allele and genotype frequencies in the BIOL 3302L population.

1. Divide into 12 separate groups with one to two people per group. Write your group’s number on the top of page UV 17.
2. Your instructor will project the data.  
   1. Determine the total number of students that typed their blood: \( n = 321 \).
   2. Fill in table UV-11 with the number of students expressing the different phenotypic traits.

**A. Rh (D antigen) Frequencies**

Remember the Rh (D) Blood Group System has one d antigen. Each individual inherits one antigen from each parent. An individual with Rh+ blood exhibits the D antigen on the surface of their red blood cells, while Rh- blood does not. The Rh blood groups are determined by a pair of alleles, with the positive allele being dominant over the negative allele.

1. What are the possible genotypes for the dominant Rh trait: _______
2. What are the possible genotypes for the recessive Rh trait: _______

**Table UV-11: ABO and Rh phenotypes expressed by the students in BIOL 3302L**

| Rh Phenotype | ABO Phenotype | Number of Students |
|--------------|---------------|--------------------|
| Rh +         | O             | 115                |
| Rh +         | AB            | 32                 |
| Rh +         | B             | 49                 |
| Rh +         | A             | 126                |
| Rh -         |               | 72                 |
