How many different types of gametes could be produced through the independent assortment by an individual with the genotype AaBBCcDdee?

Options

A. 8
B. 4
C. 2
D. 1

Answer

To determine the number of different types of gametes produced by an individual with the genotype AaBBCcDdee, we can follow these steps:

### Step 1: Identify the alleles for each gene
The genotype is AaBBCcDdee, which can be broken down into the following genes:
- A: Aa (heterozygous)
- B: BB (homozygous)
- C: Cc (heterozygous)
- D: Dd (heterozygous)
- E: ee (homozygous)

### Step 2: Determine the number of gametes for each gene
Next, we will determine how many different types of gametes can be produced from each gene:
- For gene A (Aa), there are 2 possible gametes: A and a.
- For gene B (BB), there is only 1 possible gamete: B.
- For gene C (Cc), there are 2 possible gametes: C and c.
- For gene D (Dd), there are 2 possible gametes: D and d.
- For gene E (ee), there is only 1 possible gamete: e.

### Step 3: Multiply the number of gametes
To find the total number of different types of gametes, we multiply the number of possibilities for each gene:
- Total gametes = (Number of gametes from A) × (Number of gametes from B) × (Number of gametes from C) × (Number of gametes from D) × (Number of gametes from E)

Calculating this gives:
- Total gametes = 2 (from A) × 1 (from B) × 2 (from C) × 2 (from D) × 1 (from E)
- Total gametes = 2 × 1 × 2 × 2 × 1 = 8

### Conclusion
The total number of different types of gametes that can be produced by the individual with the genotype AaBBCcDdee is **8**.
