In Andalusian fowls, the mating of black and white fowls will produce

Options

A. Black fowis
B. White fowis
C. Blue fowis
D. Grey fowis

Answer

To solve the question regarding the mating of black and white Andalusian fowls, we will analyze the genetic inheritance involved, particularly focusing on the concept of incomplete dominance.

### Step-by-Step Solution:

1. **Identify the Traits**:
- In Andalusian fowls, the black feather color is represented by the allele \( F_B \) and the white feather color by the allele \( F_W \).

2. **Understand Incomplete Dominance**:
- Incomplete dominance occurs when the phenotype of the heterozygote (the offspring with one allele from each parent) is intermediate between the phenotypes of the two homozygotes. This means that neither allele is completely dominant over the other.

3. **Set Up the Cross**:
- When black fowls (\( F_B F_B \)) are mated with white fowls (\( F_W F_W \)), the resulting offspring will be heterozygous (\( F_B F_W \)).

4. **Determine the Phenotype of the Offspring**:
- The offspring (\( F_B F_W \)) will exhibit a phenotype that is a blend of both parental traits due to incomplete dominance. In this case, the resulting color will be blue.

5. **Summarize the Results**:
- Therefore, the mating of black and white Andalusian fowls will produce fowls with blue feathers.

### Final Answer:
The mating of black and white Andalusian fowls will produce blue fowls.
