Which is used to maintain genetic trait of a green plant

Options

A. By propagating through seed germination
B. By propagating through vegetative multiplication
C. By generating hybrids through intergeneric pollination
D. By treating the seeds with gamma radiations

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the method used to maintain the genetic traits of a green plant. This involves looking at how plants can reproduce while preserving their genetic characteristics.

2. **Identifying the Method**: The key method for maintaining genetic traits in plants is through vegetative propagation or vegetative multiplication. This method allows plants to reproduce asexually.

3. **Explaining Vegetative Multiplication**: In vegetative multiplication, new plants are produced from the vegetative parts of the parent plant, such as stems, roots, or leaves. This process does not involve the formation of seeds or gametes.

4. **Genetic Uniformity**: One of the main advantages of vegetative propagation is that it results in a genetically uniform population. This means that the offspring (or clones) are genetically identical to the parent plant.

5. **Asexual Reproduction**: Since vegetative propagation is a form of asexual reproduction, there is no mixing of genetic material (no fertilization or meiosis). This lack of genetic recombination ensures that the genetic traits of the parent plant are preserved in the offspring.

6. **Comparison with Sexual Reproduction**: In contrast, sexual reproduction (which involves seeds) can lead to genetic variation due to the recombination of genes during meiosis and fertilization. This variation can alter the genetic traits of the offspring.

7. **Conclusion**: Therefore, the method used to maintain the genetic traits of a green plant is by propagating through vegetative multiplication.

**Final Answer**: By propagating through vegetative multiplication.
