For finding the different types of gametes produced by genotype AaBb, it should be crossed with genotype

Options

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

Answer

To find the different types of gametes produced by the genotype AaBb, we can follow these steps:

### Step 1: Identify the Genotype
The genotype we are working with is AaBb. This means that there are two genes, A and B, each with two alleles. A can be either dominant (A) or recessive (a), and B can be either dominant (B) or recessive (b).

### Step 2: Determine Possible Gametes
To find the different types of gametes that can be produced by the genotype AaBb, we can use the combination of alleles from each gene. The gametes are formed by taking one allele from each gene.

1. From gene A (Aa), the possible alleles are A and a.
2. From gene B (Bb), the possible alleles are B and b.

### Step 3: Combine Alleles
Now, we can combine the alleles from each gene to form the gametes:

- Combine A from A (Aa) with B from B (Bb) → AB
- Combine A from A (Aa) with b from B (Bb) → Ab
- Combine a from A (Aa) with B from B (Bb) → aB
- Combine a from A (Aa) with b from B (Bb) → ab

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

### Conclusion
Thus, the four different types of gametes produced by the genotype AaBb are AB, Ab, aB, and ab.
