Meiosis is evolutionary significant because it results in

Options

A. genetically similar daughters
B. four daughter cells
C. eggs and sperms
D. recombinations

Explanation

### Step-by-Step Solution:

1. **Understanding Meiosis**: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of gametes (sperm and egg cells). This reductional division is crucial for sexual reproduction.

**Hint**: Remember that meiosis leads to the formation of gametes with half the chromosome number.

2. **Gamete Formation**: During gametogenesis, meiosis produces gametes that contain only half the set of chromosomes compared to the parent cells. This is essential for maintaining the chromosome number across generations when fertilization occurs.

**Hint**: Focus on the importance of halving the chromosome number for the next generation.

3. **Genetic Variation**: One of the key evolutionary significances of meiosis is the introduction of genetic variation. This occurs through processes such as crossing over and independent assortment during meiosis.

**Hint**: Think about how genetic variation contributes to evolution and adaptation.

4. **Crossing Over**: During the pachytene stage of meiosis, homologous chromosomes pair up and exchange segments of genetic material. This process is known as crossing over and results in new combinations of genes.

**Hint**: Recall that crossing over is a critical mechanism for generating diversity in offspring.

5. **Recombination**: The result of crossing over is the formation of recombinant chromatids, which have a mix of genetic material from both parents. This recombination is significant because it leads to offspring that are genetically different from their parents.

**Hint**: Understand that recombination is key to evolutionary processes by creating unique genetic combinations.

6. **Conclusion**: The evolutionary significance of meiosis lies in its ability to produce genetic diversity through recombination, which enhances the adaptability and survival of species over time.

**Hint**: Summarize the importance of genetic diversity in evolution.

### Final Answer:
Meiosis is evolutionarily significant because it results in genetic recombination, which creates new combinations of genes in the offspring, enhancing genetic diversity and adaptability.
