Continued self pollination results in

Options

A. formation of unisexual flowers
B. gametes loosing vigour
C. self incompatibillity
D. inbreeding depression

Answer

**Step-by-Step Solution:**

1. **Understanding Self-Pollination**: Self-pollination occurs when pollen from the same flower fertilizes its ovules. This can happen in plants that are hermaphroditic (having both male and female reproductive organs).

2. **Identifying the Consequences of Continued Self-Pollination**: When self-pollination continues over several generations, it leads to the mating of closely related individuals. This is known as inbreeding.

3. **Defining Inbreeding Depression**: Inbreeding depression refers to the reduced biological fitness of a population due to inbreeding. This can manifest as decreased vigor, fertility, and overall health of the offspring.

4. **Evaluating the Options**:
- **Formation of Unisexual Flowers**: This is incorrect as self-pollination does not lead to the formation of unisexual flowers.
- **Gametes Losing Vigor**: This is also incorrect; gametes do not inherently lose vigor due to self-pollination.
- **Self-Incompatibility**: This is not a direct result of self-pollination; rather, it refers to a mechanism that prevents self-fertilization in some plants.
- **Inbreeding Depression**: This is the correct answer, as continued self-pollination leads to inbreeding, which results in inbreeding depression.

5. **Conclusion**: Therefore, the answer to the question "Continued self-pollination results in?" is **inbreeding depression**.
