Formation of fruit without involving gametic fusion is called

Options

A. adventitive embryony
B. polyembryony
C. parthenocarpy
D. parthenogenesis

Answer

To solve the question "Formation of fruit without involving gametic fusion is called," we can follow these steps:

### Step 1: Understand the Terms
- **Gametic Fusion**: This refers to the process where male and female gametes (sperm and egg) fuse during fertilization to form a zygote.
- **Fruit Formation**: Typically involves fertilization, where the ovule develops into a seed and the ovary develops into a fruit.

### Step 2: Identify the Options
- **A. Adventative embryonic**: This term refers to the formation of embryos from somatic cells, not directly related to fruit formation.
- **B. Polyembryonic**: This refers to the formation of multiple embryos from a single fertilized egg, which also involves gametes.
- **C. Parthenocarpy**: This is the development of fruit without fertilization, leading to seedless fruits.
- **D. Parthenogenesis**: This is a form of asexual reproduction where an egg develops into an organism without fertilization, but it does not specifically refer to fruit formation.

### Step 3: Analyze the Correct Option
- The question specifically asks for the formation of fruit without gametic fusion. Among the provided options, **C. Parthenocarpy** is the only term that fits this definition, as it describes the process of fruit development without fertilization, resulting in seedless fruits.

### Step 4: Conclusion
Thus, the correct answer is **C. Parthenocarpy**.
