Cross-pollination facilitated by dichogamy is found in: (RJ AARO Botany 2014)

✅ Explanation:
Maize is indeed a good example of a crop that utilizes dichogamy for cross-pollination.
Dichogamy is the separation in time of male and female flower maturation. In maize, the male flowers (tassel) mature and release pollen before the female flowers (silk) are receptive. This promotes cross-pollination by wind.

📌Other Options Explanations:
-Option C: Cotton: Cotton is largely self-pollinating.

🔑Key Points:
-Dichogamy refers to the maturation of sex organs at different times in plants.
-Dichogamy promotes outcrossing even in hermaphrodite species which controls genetic transmission within and among the population.
