Question

Somatic hybridization is a powerful tool in plant breeding. However, it faces certain limitations. Which of the following is NOT a typical limitation of somatic hybridization?

Mr. BALACHANDRA.N · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Somatic hybridization and its limitations
 **Related Topics**: Plant breeding, protoplast fusion, genetic engineering
 **Prerequisites**: Basic understanding of plant cell structure and genetics.
## SOLUTION PATHWAY
**Given Information**:
The question asks to identify a statement that does NOT represent a limitation of somatic hybridization.
**Method & Steps**:
1. Analyze each option to determine if it represents a known limitation of somatic hybridization.
 Reasoning: Somatic hybridization involves fusing protoplasts (plant cells without cell walls) from two different plants to create a hybrid. Several challenges arise during this process.
 Formula/Rule: N/A
2. Evaluate each option against the known limitations.
 Working:
    * **A: Regeneration of hybrid plants can be difficult:** This is a common limitation.  Successfully regenerating whole plants from fused protoplasts is often challenging.
    * **B: Protoplast fusion may be random and unpredictable:**  The fusion process isn't always precise, leading to unpredictable combinations of genetic material.
    * **C: Requirement for homozygous parental lines:** This is NOT a typical limitation.  Somatic hybridization can be performed with heterozygous lines.
    * **D: Cytoplasmic incompatibility may occur:**  Differences in cytoplasmic genomes can cause incompatibility and hinder hybrid development.
 Key Point:  Focusing on what makes an option *not* a limitation is crucial.
3. Identify the option that does not represent a limitation.
 Result: Option C is the correct answer because it's not a typical limitation of somatic hybridization.
 Verification:  The other options are all well-documented challenges in somatic hybridization.
## OPTION ANALYSIS
A ✓: Regeneration of hybrid plants is often difficult due to the complex process of plant tissue culture and regeneration.
B :x: Random and unpredictable fusion is a major drawback. The resulting hybrid may not have the desired characteristics.
C :x: Homozygous parental lines are not required; heterozygous lines can also be used.
D :x: Cytoplasmic incompatibility, arising from differences in organelles' DNA, can lead to the failure of hybrid development.
## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing somatic hybridization with other plant breeding techniques.
   How to avoid:  Clearly understand the process of somatic hybridization, including protoplast isolation, fusion, and regeneration.
  2.Overlooking the nuances of each limitation.
   How to avoid: Carefully analyze each option in the context of the somatic hybridization process.
 **Quick Tips**:
  1.Focus on the specific challenges associated with each step of somatic hybridization (protoplast isolation, fusion, selection, regeneration).
  2.Remember that somatic hybridization, while powerful, is not a perfect or straightforward technique.
