Question

One advantage of apomixis for plant breeding is:

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
 **Primary Concept**: Apomixis and its implications in plant breeding
 **Related Topics**: Plant reproduction, genetics, plant breeding techniques
 **Prerequisites**: Understanding of sexual and asexual reproduction in plants
## SOLUTION PATHWAY
**Given Information**:
The question asks for an advantage of apomixis in plant breeding.
**Method & Steps**:
1. Understand Apomixis: Apomixis is a type of asexual reproduction in plants where seeds are formed without meiosis or fertilization.  This means the offspring are genetically identical to the parent plant (clones).
2. Analyze the options in the context of apomixis:
    * **A. Increased genetic diversity:** Apomixis produces genetically identical offspring, thus reducing genetic diversity. This is a disadvantage.
    * **B. Maintaining desirable traits over generations:** Because offspring are clones, desirable traits (e.g., disease resistance, high yield) are reliably passed on to subsequent generations. This is a major advantage.
    * **C. Adaptation to changing environments:** Lack of genetic variation makes apomictic plants less adaptable to environmental changes. This is a disadvantage.
    * **D. Enhanced seed dispersal:** Apomixis doesn't directly affect seed dispersal mechanisms. This is irrelevant.
3. Identify the best advantage:
    Option B correctly identifies the primary advantage of apomixis in plant breeding: maintaining desirable traits without genetic variation.
  Result: Maintaining desirable traits over generations is the key advantage.
  Verification: The definition of apomixis and its consequences support this conclusion.
 ## OPTION ANALYSIS
A :x: Increased genetic diversity is the opposite of what apomixis does.
B ✓: Maintaining desirable traits is a direct consequence of the clonal nature of apomixis.
C :x: Apomixis reduces adaptability due to the lack of genetic variation.
D :x: Seed dispersal is not directly impacted by apomixis.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing apomixis with sexual reproduction: Remember apomixis is asexual reproduction.
  2.Focusing on disadvantages instead of advantages: Carefully analyze each option to find the benefit for plant breeding.
 **Quick Tips**:
  1.Remember the key feature of apomixis: producing genetically identical offspring.
  2.Apomixis is useful for preserving superior genotypes in plant breeding.
