Question

a population contains short plants and tall plants. the short plants are not able to compete with tall plants for sunlight. the tall plants, however, are more susceptible to wind damage. which type of selection will this population of plants most likely experience?
disruptive selection
stabilizing selection
directional selection
species selection

Explanation:

1. First, recall the definitions of each selection type:

• Disruptive selection: Favors extreme phenotypes over intermediate ones, leading to a population split.
• Stabilizing selection: Favors intermediate phenotypes, reducing variation.
• Directional selection: Favors one extreme phenotype, shifting the population mean.
• Species selection: Acts on species, not individual populations.

1. In this case, short plants struggle with sunlight (disadvantage of being too short), tall plants struggle with wind (disadvantage of being too tall). Intermediate - height plants (not mentioned but implied as a middle ground) would likely be favored as they avoid both disadvantages. This fits stabilizing selection, which selects against extreme phenotypes (very short or very tall here) and for the intermediate.

Answer:

stabilizing selection
