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 alleles in the genotype
The given genotype is AABBCcDdee. We can break this down into the following alleles:
- A: homozygous (AA)
- B: homozygous (BB)
- C: heterozygous (Cc)
- D: homozygous (DD)
- e: heterozygous (ee)

### Step 2: Determine the number of heterozygous loci
In the genotype, we identify the loci that are heterozygous:
- C (Cc) is heterozygous.
- e (ee) is also heterozygous.

So, we have 2 heterozygous loci: C and e.

### Step 3: Use the formula to calculate the number of gametes
The formula to calculate the number of different types of gametes is given by \(2^N\), where \(N\) is the number of heterozygous loci.

In this case, \(N = 2\) (from Cc and ee).

### Step 4: Calculate the number of gametes
Now, we apply the formula:
\[ \text{Number of gametes} = 2^N = 2^2 = 4 \]

### Conclusion
Therefore, the individual with the genotype AABBCcDdee produces **4 types of gametes**.
