DENDROLOGY

Detailed explanation-1: -Cross-pollination or xenogamy enables the fusion of two genetically distinct plant characters, belonging to the same species. Therefore, it introduces genetic recombination and variations in plants due to the fusion of gametes that are genetically distinct.

Detailed explanation-2: -cross-pollination, also called heterogamy, type of pollination in which sperm-laden pollen grains are transferred from the cones or flowers of one plant to egg-bearing cones or flowers of another.

Detailed explanation-3: -In nature, cross-pollination occurs when pollen from one plant is transferred to another plant, resulting in healthier offspring and new plant varieties. It’s essential for genetic variation, increasing plants’ diversity and adaptability in changing environments.

Detailed explanation-4: -Various methods of cross pollination are entamophily (pollination by insects), anemophily (pollination by wind), hydrophily (pollination by water), zoophily (pollination by animals) and ornithophily(pollination by birds).
