Which one of the following methods is commonly used tomaintain the genetic of a givan plant?

Options

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

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks about the method commonly used to maintain the genetic traits of a given plant.

2. **Identify Propagation Methods**: There are two primary methods of plant propagation: sexual (through seeds) and asexual (through vegetative multiplication).

3. **Analyze Sexual Propagation**: When plants are propagated through seeds, genetic variation occurs due to the segregation of genes during meiosis. This means that the offspring may not have the same genetic traits as the parent plant.

4. **Analyze Asexual Propagation**: In contrast, vegetative multiplication (asexual propagation) involves methods such as cuttings, layering, or grafting. This method produces clones, which are genetically identical to the parent plant, thus maintaining the genetic traits.

5. **Conclusion**: Since the question is about maintaining genetic traits, the method that ensures genetic uniformity is vegetative multiplication. Therefore, the correct answer is the method of vegetative multiplication.

**Final Answer**: The method commonly used to maintain the genetic traits of a given plant is **vegetative multiplication**.
