In order to find out the different types of gametes produced by a pea plant having the genotype AaBb. It should be crossed to a plant with the genotype

Options

A. aaBB
B. AaBb
C. AaBB
D. aabb

Answer

To determine the different types of gametes produced by a pea plant with the genotype AaBb, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Genotype**: The genotype of the pea plant is AaBb. This means it has two genes, A and B, each with two alleles: A (dominant) and a (recessive) for the first gene, and B (dominant) and b (recessive) for the second gene.

2. **Determine Possible Gametes**: To find out the different types of gametes that can be produced, we need to consider all combinations of the alleles from both genes. Each gamete will receive one allele from each gene.

3. **List the Alleles**:
- For gene A: The alleles are A and a.
- For gene B: The alleles are B and b.

4. **Combine Alleles**: The possible combinations of alleles (gametes) can be formed by taking one allele from each gene:
- AB (A from gene A and B from gene B)
- Ab (A from gene A and b from gene B)
- aB (a from gene A and B from gene B)
- ab (a from gene A and b from gene B)

5. **Conclusion**: Therefore, the different types of gametes produced by the pea plant with genotype AaBb are AB, Ab, aB, and ab.
