Which of the following method would not produce clones ?

Options

A. Double fertilization
B. Apomixis
C. Vegetative reproduction
D. Tissue culture

Answer

To determine which method would not produce clones, let's analyze each option provided:

1. **Double Fertilization**:
- This process occurs in angiosperms (flowering plants) where two male gametes from the pollen tube fertilize the egg cell and the central cell. The first fertilization results in the formation of a zygote, while the second leads to the formation of endosperm. Since this process involves fertilization and the combination of genetic material from two parents, it does not produce clones, which are genetically identical individuals.

2. **Apomixes**:
- Apomixes is a form of asexual reproduction where seeds are produced without fertilization. The offspring are genetically identical to the parent plant, hence they are considered clones.

3. **Vegetative Reproduction**:
- This is another form of asexual reproduction where new plants grow from parts of the parent plant, such as stems, roots, or leaves. Since the offspring are genetically identical to the parent, they are also considered clones.

4. **Tissue Culture**:
- In tissue culture, a part of the plant (called explant) is cultured in a nutrient medium to grow new plants. All the new plants produced through this method are genetically identical to the original plant, thus they are clones.

Based on this analysis, the method that does not produce clones is **Double Fertilization**.

**Final Answer**: Double Fertilization
