Imagine this field of flowers. Environmental conditions change. The climate becomes colder and the winds become fierce. Such a c
limate favors plants that grow close to the ground, have needles, and have bright flowers. In this field of flowers, only the shortest plants survive. Over time, the population consists of very short, low growing plants. This is also an example of ____________ selection. A) directional B) disruptive C) environmental D) stabalizing
Directional selection is usually defined as a type of natural selection method where the genetic variance of a particular population moves towards a new type of phenotype due to their exposure to the frequent changes that occur in the environment.
This method leads to a decreasing rate of genetic variability. In nature, this method results in the evolutionary trend of a population towards one particular end of the trait spectrum.
