In a case of red and white flowered Snapdragon, `F_(1)` plants will have flowers

Options

A. Red
B. White
C. Both A and B
D. Pink

Answer

To solve the question regarding the flower color of `F_(1)` plants in Snapdragon, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding the Parental Generation**:
- We have two types of snapdragon flowers: red and white.
- The red flower is represented by the dominant allele (R), while the white flower is represented by the recessive allele (r).

2. **Crossing the Parental Generation**:
- When we cross a red flower (RR) with a white flower (rr), we can set up the following cross:
- Parent 1: RR (Red)
- Parent 2: rr (White)

3. **Determining the F1 Generation**:
- The offspring (F1 generation) will inherit one allele from each parent.
- Therefore, all F1 plants will have the genotype Rr (one R from the red parent and one r from the white parent).

4. **Phenotype of the F1 Generation**:
- Since the R allele is dominant over the r allele, the phenotype of the F1 generation will be determined by the presence of the R allele.
- However, in snapdragons, there is a phenomenon known as incomplete dominance, where the heterozygous condition (Rr) results in a blend of the two parental phenotypes.
- Thus, the F1 plants will have pink flowers.

5. **Conclusion**:
- The F1 generation of snapdragon flowers will have pink flowers.

### Final Answer:
The F1 plants will have pink flowers.
