How many different types of gametes are formed from AaBbCcDdEe?

Options

A. 2
B. 8
C. 16
D. 32

Answer

To determine how many different types of gametes can be formed from the genotype AaBbCcDdEe, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Genotype**: The given genotype is AaBbCcDdEe. Each letter represents a gene, where uppercase letters indicate dominant alleles and lowercase letters indicate recessive alleles.

2. **Count the Heterozygous Genes**: In the genotype, we need to identify how many genes are heterozygous (having both dominant and recessive alleles).
- A (Aa) - heterozygous
- B (Bb) - heterozygous
- C (Cc) - heterozygous
- D (Dd) - heterozygous
- E (Ee) - heterozygous

All five genes (A, B, C, D, E) are heterozygous.

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

4. **Calculate the Number of Gametes**: Since we have 5 heterozygous gene pairs (A, B, C, D, E):
\[ n = 5 \]
Therefore, the number of different types of gametes is:
\[ 2^5 = 32 \]

5. **Conclusion**: The total number of different types of gametes that can be formed from the genotype AaBbCcDdEe is 32.

### Final Answer:
The number of different types of gametes formed from AaBbCcDdEe is **32**.
