selection.

The type of natural selection that favors individuals with intermediate phenotypes and selects against those with extreme phenotypes is called 
 selection.

The question presents a fill-in-the-blank about a specific type of natural selection: 'The type of natural selection that favors individuals with intermediate phenotypes and selects against those with extreme phenotypes is called ____ selection.'

Option 1: 空白1. In this format, 空白1 represents the blank to be filled. To determine the correct term, we consider the definitions of the common modes of natural selection.

- Stabilizing selection (the concept described) favors average or intermediate phenotypes and disfavors extreme variations. This results in reduced variation around the mean and is typical in stable environments where intermediate traits confer the best fit.
- Directional selection would favor one extreme phenotype, shifting the population mean in a particular direction, which is the opposite of what the question describes.
- Disruptive selection would favor the two or more extreme phenotypes over the intermediate, leading to a bimodal distribution rather than an intermediate peak.

Since the statement explicitly mentions favoring intermediates and acting against extremes, stabilizing selection is the best-fitting concept. The placeholder 空白1 should be filled with the term that captures that idea, namely 'stabilizing' in a complete answer.

In summary, the description matches stabilizing selection, as it concentrates toward the average phenotype and reduces extreme forms in the population.
