Stabilizing selection is the opposite of disruptive selection. Instead of favoring individuals with extreme phenotypes, it favors the intermediate variants. Disruptive selection is an evolutionary force that drives a population apart. The disruptive selection will cause organsisms with intermediate traits to reproduce less, and will allow those organisms with extreme traits to reproduce more. This causes the alleles for the extreme traits to increase in frequency. Over time, … See more 1. A population of deer has legs of very different lengths.
