Identify the correct number of gametes, genotypes and phenotypes respectively, produced in the self pollination of plant with genotype of AaBBCCDdEE

Options

A. 3,8,3
B. 4,9,4
C. 4,6,8
D. 4,8,4

Answer

To solve the problem of identifying the correct number of gametes, genotypes, and phenotypes produced in the self-pollination of a plant with the genotype AaBBCCDdEE, we can follow these steps:

### Step 1: Identify the Gametes
1. **Identify the alleles for each gene**:
- For A: Aa → can produce gametes A or a
- For B: BB → can only produce gamete B
- For C: CC → can only produce gamete C
- For D: Dd → can produce gametes D or d
- For E: EE → can only produce gamete E

2. **List the possible combinations of gametes**:
- From A: A, a
- From B: B
- From C: C
- From D: D, d
- From E: E

3. **Combine the alleles to find the total number of gametes**:
- The combinations are:
- AD, AE
- Ad, AE
- aD, AE
- ad, AE
- Thus, the total number of gametes is 4.

### Step 2: Determine the Genotypes
1. **Set up a Punnett square** for the two heterozygous genes (A and D):
- The gametes from Aa are A and a.
- The gametes from Dd are D and d.

2. **Fill in the Punnett square**:
- The combinations will be:
- AA DD
- AA Dd
- Aa DD
- Aa Dd
- aa DD
- aa Dd

3. **Count the unique genotypes**:
- The unique genotypes are:
- AADD
- AADd
- AaDD
- AaDd
- aaDD
- aaDd
- Thus, the total number of unique genotypes is 9.

### Step 3: Determine the Phenotypes
1. **Identify the dominant traits**:
- Since A, B, C, and E are homozygous dominant, they will express the dominant phenotype.
- The presence of at least one dominant allele (A or D) will result in the dominant phenotype.

2. **Count the unique phenotypes**:
- The phenotypes will be based on the dominant alleles:
- Dominant for A (AA or Aa)
- Dominant for B (BB)
- Dominant for C (CC)
- Dominant for E (EE)
- For D, we have two possibilities (D or d).
- Thus, the unique phenotypes are:
- Dominant (A, B, C, E) with D
- Dominant (A, B, C, E) with d
- Therefore, the total number of phenotypes is 4.

### Final Answer:
- **Number of Gametes**: 4
- **Number of Genotypes**: 9
- **Number of Phenotypes**: 4
