How many different kinds of gametes will be produced by a plant having the genotype AABbCCddEEff ?

Options

A. eight
B. Four
C. thirty two
D. Two

Answer

To determine how many different kinds of gametes will be produced by a plant with the genotype AABbCCddEEff, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Genotype**: The given genotype is AABbCCddEEff.

2. **Classify Each Locus**:
- **AA**: Homozygous (both alleles are the same)
- **Bb**: Heterozygous (alleles are different)
- **CC**: Homozygous
- **dd**: Homozygous
- **EE**: Homozygous
- **ff**: Homozygous

3. **Count the Heterozygous Loci**:
- From the classification, we see that only **Bb** is heterozygous.
- Therefore, there is **1 heterozygous locus**.

4. **Use the Formula for Gametes**:
- The formula to calculate the number of different gametes is \(2^n\), where \(n\) is the number of heterozygous loci.
- Here, \(n = 1\).

5. **Calculate the Number of Gametes**:
- Substitute \(n\) into the formula:
\[ 2^1 = 2 \]
- Therefore, the plant will produce **2 different kinds of gametes**.

6. **List the Gametes**:
- The two types of gametes can be derived from the heterozygous locus (Bb):
- **Gamete 1**: A, B, C, d, E, f (from AABbCCddEEff)
- **Gamete 2**: A, b, C, d, E, f (from AABbCCddEEff)
- The only difference is in the B allele.

### Final Answer:
The plant with the genotype AABbCCddEEff will produce **2 different kinds of gametes**.
