In meiosis, the daughter cells are not similar to that of parent because of :

Options

A. Crossing over
B. Synapsis
C. Both (a) and (b)
D. None of these

Answer

### Step-by-Step Solution

1. **Understanding Meiosis**: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse daughter cells. This process is crucial for sexual reproduction.

2. **Homologous Chromosomes**: During meiosis, homologous chromosomes (one from each parent) pair up. Each homologous chromosome consists of two sister chromatids.

3. **Crossing Over**: The key process that leads to genetic variation in the daughter cells is called crossing over. This occurs during prophase I of meiosis when non-sister chromatids of homologous chromosomes exchange segments of genetic material.

4. **Genetic Variation**: Because of crossing over, the chromatids that result from this exchange contain a mix of genetic information from both the maternal and paternal chromosomes. This results in daughter cells that are genetically different from the parent cell.

5. **Conclusion**: Therefore, the reason the daughter cells are not similar to the parent cell in meiosis is primarily due to crossing over, which introduces genetic variation.
