Blue poppies native to China are grown at a plant-breeding center in California, where those with the thickest leaves survive an
d reproduce best in the drier climate. This evolutionary adaptation of the poppies to their new environment is due to _____. A) genetic driftB) stabilizing selectionC) diversifying selectionD) neutral variationE) directional selection
These selections occur in a given environment to either increase, decrease or maintain the genetic variance of the population.
A type of natural selection in which the phenotype of the species of a given population tends to shift away from the mean and towards one extreme phenotype is known as directional selection.
In the given situation, it is given that the extreme phenotype of having thickest leaves is being favored in drier climate and hence, this is an example of directional selection.
