Law of segregation can be associated with

Options

A. Anaphase
B. Anaphase I
C. Anaphase II
D. All of these

Answer

To solve the question regarding the association of the law of segregation, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Law of Segregation**:
- The Law of Segregation, proposed by Gregor Mendel, states that during the formation of gametes (sperm and egg), the alleles for a trait separate so that each gamete carries only one allele for each gene. This means that offspring inherit one allele from each parent.

2. **Identify the Process Involved**:
- The law of segregation is fundamentally linked to the process of meiosis, which is the type of cell division that produces gametes. Meiosis consists of two rounds of division: meiosis I and meiosis II.

3. **Focus on Meiosis I**:
- The key phase where the law of segregation is most relevant is during meiosis I, specifically during anaphase I. This is when homologous chromosomes are separated and pulled to opposite poles of the cell.

4. **Analyze the Options**:
- **Anaphase**: This is a general term and does not specify which meiotic division it refers to.
- **Anaphase I**: This is the correct phase where the law of segregation is observed, as homologous chromosomes (and thus their alleles) are segregated into different gametes.
- **Anaphase II**: In this phase, sister chromatids are separated, but there is no crossing over or exchange of alleles, making it irrelevant to the law of segregation.
- **All of these**: This option is incorrect because only anaphase I is associated with the law of segregation.

5. **Conclusion**:
- Based on the analysis, the law of segregation is specifically associated with **anaphase I** of meiosis.

### Final Answer:
The law of segregation can be associated with **anaphase I**.
