Seed Bed Selection Can Result in the Alteration of a Population

question 124

Multiple Choice

Seed bed selection can result in the alteration of a population of wild plants because:

• A) larger seeds that sprout first and grow rapidly are more likely to survive when the sprouts are thinned
• B) smaller seeds that sprout late are more likely to be left alone to propagate while the quick sprouters will be harvested and eaten and less likely to propagate
• C) the seed bed is more gentle than a natural environment, and new varieties unlikely to survive in the wild can flourish in the seed bed
• D) there is greater opportunity for hybridization in the seed bed, producing new species of plants
