- Intraspecific cross pollination refers to the transfer of pollen from the anther of one flower to the stigma of another flower of the same species.

2. **Identifying the Options:**
- The options given are:
- a) Allogamy
- b) Gatenogamy
- c) Xenogamy
- d) Autogamy

3. **Analyzing Each Option:**
- **Allogamy:** This is the correct term for cross pollination where pollen is transferred between flowers of the same species but on different plants.
- **Gatenogamy:** This term does not refer to any recognized type of pollination and seems to be a misnomer.
- **Xenogamy:** This refers to cross pollination between flowers of different species, not intraspecific.
- **Autogamy:** This is self-pollination, where pollen from a flower fertilizes its own stigma, which does not involve cross pollination.

4. **Conclusion:**
- The correct answer is **Allogamy**, as it specifically describes intraspecific cross pollination.
