The law of segeration of characters postulated by Mendel can be related to

Options

A. The presence of two alleles for each character in a somatic cell
B. A gamate receiving only one of the two homologous chromosomes during meisois
C. Presence of both genes on the same chromosomes
D. None of the above

Answer

### Step-by-Step Solution

1. **Understanding Mendel's Law of Segregation**:
- Mendel's Law of Segregation states that during the formation of gametes, the two alleles responsible for a trait separate from each other. Each gamete carries only one allele for each gene.

2. **Analyzing the Options**:
- **Option A**: "The presence of two alleles for each character in a somatic cell."
- This option refers to the fact that somatic cells contain two alleles for each gene (one from each parent). However, it does not explain how these alleles segregate during gamete formation. Therefore, this option is incorrect.

- **Option B**: "A gamete receiving only one of two homologous chromosomes during meiosis."
- This option accurately describes the process of segregation. During meiosis, homologous chromosomes are separated, and each gamete ends up with only one chromosome from each pair, which corresponds to one allele for each gene. This is directly related to Mendel's Law of Segregation and is the correct answer.

- **Option C**: "Presence of both genes on the same chromosome."
- This option does not relate to the law of segregation. The presence of genes on the same chromosome does not explain how alleles segregate during gamete formation. Thus, this option is also incorrect.

- **Option D**: "None of the above."
- Since we have identified Option B as correct, this option is incorrect.

3. **Conclusion**:
- The correct answer is **Option B**: "A gamete receiving only one of two homologous chromosomes during meiosis."
