What should be the composition of gametes ?

Options

A. GgLl
B. Ggl
C. Gg
D. Gl

Answer

To determine the composition of gametes from the given options, we need to understand the basic principles of genetics, particularly how alleles segregate during gamete formation.

### Step-by-Step Solution:

1. **Understanding Alleles**:
- Alleles are different forms of a gene. For example, if we have a gene represented as "G" (dominant) and "g" (recessive), an organism with genotype "Gg" has one dominant and one recessive allele.

2. **Gamete Formation**:
- During gamete formation (meiosis), each gamete receives only one allele from each gene pair. This means that if an organism has two alleles for a trait, it will produce gametes that contain only one of those alleles.

3. **Analyzing the Options**:
- **Option 1: Capital G small g capital L small l**: This option contains both alleles for two traits, which is incorrect for gametes.
- **Option 2: Capital G small g small l**: This option also contains both alleles for two traits, which is incorrect for gametes.
- **Option 3: Capital G small g**: This option contains both alleles for one trait, which is incorrect for gametes.
- **Option 4: Capital G small l**: This option contains one allele from each trait, which is correct for gametes.

4. **Conclusion**:
- The correct composition of gametes should only include one allele from each gene. Therefore, the correct answer is **Option 4: Capital G small l**.
