Gametes of AaBb individuals can be:

Options

A. Aa,Bb
B. AB,ab
C. AB,ab,aB
D. AB,Ab,aB,ab.

Answer

To determine the possible gametes of an individual with the genotype AaBb, we can follow these steps:

### Step 1: Understand the Genotype
The genotype AaBb consists of two gene pairs:
- The first gene pair consists of alleles A (dominant) and a (recessive).
- The second gene pair consists of alleles B (dominant) and b (recessive).

### Step 2: Identify Alleles
From the genotype AaBb, we can identify the alleles:
- For the first gene (A/a), the individual can contribute either A or a.
- For the second gene (B/b), the individual can contribute either B or b.

### Step 3: Use the Principle of Independent Assortment
According to the principle of independent assortment, the alleles of different genes segregate independently during gamete formation. This means we can combine the alleles from the two gene pairs in all possible ways.

### Step 4: Combine Alleles to Form Gametes
We can combine the alleles from the two gene pairs:
1. Combine A (from A/a) with B (from B/b) → AB
2. Combine A (from A/a) with b (from B/b) → Ab
3. Combine a (from A/a) with B (from B/b) → aB
4. Combine a (from A/a) with b (from B/b) → ab

### Step 5: List the Possible Gametes
The possible gametes from the genotype AaBb are:
- AB
- Ab
- aB
- ab

### Conclusion
Thus, the gametes of an AaBb individual can be AB, Ab, aB, and ab.
