Question
Please fill in UV-13: Tables A and B and use the Hardy-Weinberg Equations

Transcribed Image Text:The document appears to be educational material about the ABO blood group system, focusing on genetic traits and their frequencies. It includes questions to guide understanding, and a table for recording allele and genotype frequencies as well as population estimates. The content is likely designed for use with the Hardy-Weinberg equilibrium to calculate and predict genetic variations.
**Text Content:**
**ABO Blood Group System Overview:**
1. Exhibits three alleles: \(I^A\), \(I^B\), and i.
2. These alleles are on one locus; \(I^A\) and \(I^B\) are codominant over i.
3. Use the Hardy-Weinberg equation for calculations involving these alleles.
**Questions:**
7. What is the codominant phenotypic trait?
- (Answer: AB)
8. What is the recessive phenotypic trait?
- (Answer: O)
9. What are the possible genotypes for these traits?
**Table UV.13: A. Allele and B. Genotype frequencies and population estimates for the A and B antigens.**
- Section A: Alleles and Dominance Frequencies:
- p
- p\(^{2}\)
- q
- q\(^{2}\)
- 2pq
- Total =
- Section B: Genotype and Phenotype Frequencies:
- Genotype
- Phenotypic Trait
- Genotype Frequencies
- Population Estimates
- Total =
**Tasks:**
10. Calculate allele and genotype frequencies for the B383012L population.
11. Fill in Table UV.13 with the frequencies and estimates in sections 3 and 4 using the Hardy-Weinberg equation and formula.
**Graphs/Diagrams Explanation:**
There is a table (Table UV.13) divided into two primary sections:
1. **Allele Frequencies (Section A)**:
- Lists potential alleles and the calculations needed to determine their frequencies and dominance.
2. **Genotype Frequencies (Section B)**:
- Includes columns for Genotype, Phenotypic Trait, Genotype Frequencies, and Population Estimates.
This setup enables calculation and visualization of genetic frequencies within a population.

Transcribed Image Text:**Part 5: Calculating Frequencies**
Over several semesters, a population of ISU students from the Anatomy and Physiology I Laboratory typed their blood. In lab today, we will use their results to predict allele and genotype frequencies in the Biol 3302L population.
- Divide into 12 separate groups with one to two people per group. Write your group’s number on the top of page UV-17.
1. Determine the total number of students that typed their blood: \( n = 322 \).
2. Fill in Table UV-11 with the number of students expressing the different phenotypic traits.
**A. Rh (D antigen) Frequencies**
Remember the Rh Blood Group System has one locus that exhibits two (2) alleles: D and d. There are two phenotypes expressed: Rh+ and Rh-. The Rh blood groups are determined by the presence of two possible alleles for the D antigen protein on red blood cells: a dominant allele (D) which encodes for the antigen, and a recessive allele (d) which does not encode for the antigen.
3. What are the possible genotypes (s) for the dominant Rh trait: DD, Dd
4. What are the possible genotypes for the recessive Rh trait: dd
**Table UV-11**: ABO and Rh phenotypes expressed by the students in Biol 3302L.
| Rh Phenotype | Rh+ | Rh- |
|--------------|-----|-----|
| Number of Students | 250 | 72 |
| ABO Phenotype | O | AB | B | A |
|---------------|----|----|---|---|
| Number of Students | 115 | 32 | 49 | 126 |
*(The total number of students: 322.)*
