The number of different types of gametes produced from a plant with genotype Aa Bb Cc is

Options

A. 2
B. 8
C. 4
D. 16

Answer

To determine the number of different types of gametes produced from a plant with the genotype Aa Bb Cc, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Genotype**: The genotype given is Aa Bb Cc. This indicates that the plant is heterozygous for three different traits (A, B, and C).

2. **Count the Heterozygous Alleles**:
- For A, there are two alleles (A and a) → heterozygous
- For B, there are two alleles (B and b) → heterozygous
- For C, there are two alleles (C and c) → heterozygous
- Total number of heterozygous pairs (n) = 3 (one for each trait).

3. **Use the Formula for Gametes**: The formula to calculate the number of different types of gametes is:
\[ \text{Number of Gametes} = 2^n \]
where \( n \) is the number of heterozygous pairs.

4. **Calculate the Number of Gametes**:
- Substitute \( n = 3 \) into the formula:
\[ \text{Number of Gametes} = 2^3 = 8 \]

5. **List the Possible Gametes**: To verify, we can list the combinations of alleles:
- Possible combinations:
1. ABC
2. ABc
3. AbC
4. Abc
5. aBC
6. aBc
7. abC
8. abc

This confirms that there are indeed 8 different types of gametes.

### Final Answer:
The number of different types of gametes produced from a plant with genotype Aa Bb Cc is **8**.
