Occurs when male and female gametes fuse to make a seed

Detailed explanation-1: -In contrast, cross-pollination leads to greater genetic diversity because the male and female gametophytes are derived from different plants. Because cross-pollination allows for more genetic diversity, plants have developed many ways to avoid self-pollination.
Detailed explanation-2: -When the pollen transfer happens within the same flower, it is called “self-pollination.” When it occurs between different flowers, it is “cross-pollination.” Cross-pollination is preferable to self-pollination because it produces more genetic diversity in the plant populations.
Detailed explanation-3: -Self-pollination increases genetic uniformity and decreases genetic variation. Cross-pollination decreases genetic uniformity and increases genetic variation. Causes inbreeding.
Detailed explanation-4: -Pollen, looking like insignificant yellow dust, bears a plant’s male sex cells and is a vital link in the reproductive cycle. With adequate pollination, wildflowers: Reproduce and produce enough seeds for dispersal and propagation. Maintain genetic diversity within a population.
