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

Explanation

To solve the problem of finding out the different types of gametes produced by a pea plant with the genotype AaBb, we need to perform a test cross. Here’s the step-by-step solution:

### Step 1: Understand the Genotype
The genotype of the pea plant is AaBb. This means that the plant is heterozygous for both traits (A and B).

### Step 2: Identify the Gametes
To find out the different types of gametes produced by the genotype AaBb, we need to determine the combinations of alleles that can be formed.

- The alleles for A are A and a.
- The alleles for B are B and b.

### Step 3: Use the FOIL Method
Using the FOIL (First, Outside, Inside, Last) method, we can combine the alleles:
- First: A from A and B from B → AB
- Outside: A from A and b from b → Ab
- Inside: a from a and B from B → aB
- Last: a from a and b from b → ab

### Step 4: List the Gametes
The gametes produced by the genotype AaBb are:
1. AB
2. Ab
3. aB
4. ab

### Step 5: Perform a Test Cross
To determine the genotype of the pea plant, we perform a test cross. A test cross involves crossing the heterozygous plant (AaBb) with a pure recessive homozygous plant (aabb).

### Conclusion
The correct genotype to cross with AaBb in order to find out the different types of gametes is aabb.

### Final Answer
The plant with the genotype to be crossed with AaBb is aabb.
