Question

Quizplus · Accepted Answer

Population 4, with 500 plants having bisexual, self-sterile flowers that require cross-pollination, would likely have the highest genetic diversity due to the necessity of cross-pollination. This genetic diversity increases the population's ability to adapt to environmental changes, making it more likely to survive drastic environmental changes.
