How many types of gametes are produced from individual of AABBCcDdee genotype

Options

A. 4
B. 8
C. 5
D. 7

Answer

To determine how many types of gametes are produced from an individual with the genotype AABBCcDdee, we can follow these steps:

### Step 1: Identify the genotype
The given genotype is AABBCcDdee.

### Step 2: Classify the alleles
Identify which alleles are homozygous and which are heterozygous:
- **AAB**: Homozygous (AA and BB)
- **Cc**: Heterozygous (C and c)
- **D**: Homozygous (D)
- **ee**: Homozygous (ee)

### Step 3: Count the heterozygous alleles
From the classification:
- There is **1 heterozygous pair** (Cc).
- The formula for calculating the number of gametes is based on the number of heterozygous alleles.

### Step 4: Apply the formula
The formula to calculate the number of gametes is:
\[ \text{Number of gametes} = 2^n \]
where \( n \) is the number of heterozygous pairs.

In this case, \( n = 1 \) (since there is one heterozygous pair, Cc).

### Step 5: Calculate the number of gametes
Substituting \( n \) into the formula:
\[ \text{Number of gametes} = 2^1 = 2 \]

### Step 6: Conclusion
Thus, the individual with the genotype AABBCcDdee can produce **2 types of gametes**.
