**Exploring Genetics: Guinea Pig Hair Length**

*In this section, we will explore genetic inheritance using guinea pigs as a model organism. This experiment demonstrates how different traits, such as hair length, are passed from parents to offspring.*

### Short Hair vs. Long Hair in Guinea Pigs

1. **Genetic Background**: 
   - The allele for short hair is dominant over the allele for long hair.

2. **Experiment 1**: 
   - **Objective**: Cross two guinea pigs that are both heterozygous for hair length.
   - **Parent 1 Genotype**: Indicate here.
   - **Parent 2 Genotype**: Indicate here.

3. **Gametes Formation**: 
   - Parent 1 Gametes: Indicate here.
   - Parent 2 Gametes: Indicate here.

4. **Phenotype Prediction**:
   - Use a Punnett Square to predict the offspring phenotypes.

5. **Results Interpretation**:
   - **Genotype Ratio**: Indicate expected ratio.
   - **Phenotype Ratio**: Indicate expected ratio.

### True-Breeding Guinea Pigs

1. **Experiment 2**: 
   - **Objective**: Cross two true-breeding short-haired guinea pigs.
   - **Parent 1 Genotype**: Indicate here.
   - **Parent 2 Genotype**: Indicate here.

2. **Gametes Formation**:
   - Parent 1 Gametes: Indicate here.
   - Parent 2 Gametes: Indicate here.

3. **Phenotype Prediction**:
   - Use a Punnett Square to predict the offspring phenotypes.

4. **Results Interpretation**:
   - **Genotype Ratio**: Indicate expected ratio.
   - **Phenotype Ratio**: Indicate expected ratio.

*For further clarification, refer to the detailed diagrams included in the laboratory manual.*

> **Note**: The exercise and results are designed to help students understand basic genetic principles and practices.

## Exercise on Plant Genetics and Flower Color Inheritance

### Problem 8

**Scenario**: Some plants produce different colored flowers, with purple flowers as a dominant trait and white flowers as a recessive trait. The exercise involves crossing two white-flowered plants.

- **Plant One**:
  - Genotype: __________
  - Gametes: __________
  - Phenotype: __________

- **Plant Two**:
  - Genotype: __________
  - Gametes: __________
  - Phenotype: __________

- **Punnett Square**: Complete the Punnett square to illustrate the genetic cross.

**Questions**:
- Genotype ratio: __________
- Phenotype ratio: __________
- What percentage of their offspring would be expected to be white-flowered?

### Problem 9

**Scenario**: A white flowered plant is crossed with a plant that is heterozygous.

- **White Flowered Plant**:
  - Genotype: __________
  - Gametes: __________
  - Phenotype: __________

- **Heterozygous Plant**:
  - Genotype: __________
  - Gametes: __________
  - Phenotype: __________

- **Punnett Square**: Complete the Punnett square to illustrate the genetic cross.

**Questions**:
- Genotype ratio: __________
- Phenotype ratio: __________
- What percentage of their offspring would be expected to be white-flowered?

### Notes

- **Dominant Trait**: Purple flowers
- **Recessive Trait**: White flowers

This exercise aims to help students understand Mendelian genetics principles, specifically how dominant and recessive traits are passed from parents to offspring through gametes. The use of Punnett squares will guide students in predicting the genotype and phenotype ratios of offspring.

### Presentation

- Presented as a blank form for students to fill in genotypes, gametes, and phenotypes.
- Students should calculate and fill in the genotype and phenotype ratios after completing the Punnett squares.
- Discussion may focus on understanding and visualizing inheritance patterns, with purple being the dominant trait over white.

Expert Solution
Step 1

Based on monohybrid cross Mendel proposed law of dominance and law of segregation and based on dihybrid cross he proposed law of independent assortment. These laws are the first scientific basis of inheritance and variations.
