Question

In tomatoes, tall plant (D) is dominant over dwarf plant (d) and smooth fruit (H) is dominant over hairy fruit (h). A farmer crosses a tall plant with smooth tomatoes (plant A) with a dwarf and hairy fruit plant (plant B) and obtains the following results:

                                                     

 

Phenotype                                               Offspring                                                 

Tall & smooth fruit                                        3

Tall and hairy fruit                                       84

Dwarf and smooth fruit                               88

Dwarf & hairy fruit                                        4

 

 

Which of the following can be used to represent the genotype of plant A in the question above?   (lines represent homologous chromosomes)

Title: Genetic Analysis of Plant Phenotypes

**Item 6**

*Phenotype and Offspring Results:*

- Tall & smooth fruit: 3
- Tall and hairy fruit: 84
- Dwarf and smooth fruit: 88
- Dwarf & hairy fruit: 4

**Question:**

Which of the following can be used to represent the genotype of plant A in the question above? (Lines represent homologous chromosomes)

**Options:**

1. 
   ```
   d  h
   ——  
   d  h
   ```

2. 
   ```
   D  h
   ——  
   d  H
   ```

3. 
   ```
   D  H
   ——  
   d  h
   ```

4. 
   ```
   D  d
   ——  
   H  h
   ```

5. 
   ```
   D  H
   ——  
   D  H
   ```

*Diagram Explanation:*

The diagram shows homologous chromosome pairs, each with specific alleles denoted by letters (D, d, H, h). The lines separating the alleles represent homologous chromosomes. Each option presents a different combination of alleles that could explain the observed phenotypic ratios.
