Diversifying selection can also occur when environmental changes favor individuals on either end of the phenotypic spectrum. Imagine a population of mice living at the beach where there is light-colored sand interspersed with patches of tall grass.

Diversifying selection. Two or more divergent phenotypes in an environment may be favoured simultaneously by diversifying selection. (See the right column of the figure.) Other articles where Disruptive selection is discussed: evolution: Diversifying selection: Two or more divergent phenotypes in an environment may be favoured simultaneously by diversifying selection. (See the right column of the figure.) No natural environment is homogeneous; rather, the environment of any plant or animal population is a mosaic consisting of more or… Put another way, there may be balancing selection for the same ovipositor length in all first generation bivoltine crickets, while diversifying selection among populations with differing season lengths is the norm for crickets producing overwintering eggs. 2019-01-19 · Stabilizing selection in evolution is a type of natural selection that favors the average individuals in a population.

Diversifying. Diversifying selection can also occur when environmental changes favor individuals on either end of the phenotypic spectrum.

Background: The presence of intraspecific color polymorphism can have multiple impacts on the ecology of a species; as a consequence, particular color morphs may be strongly selected for in a given habitat type. For example, the asp viper (Vipera aspis) shows a high level of color polymorphism. A blotched morph (cryptic) is common throughout its range (central and western Europe), while a

uBS is approximately twice as computationally efficient as 2020-04-03 · Examples of directional selection include giraffes that have long necks and the darkening of London's peppered moths after the Industrial Revolution. Directional selection is the shift of the population of one species towards a certain phenotype.

2012-07-12 · However, these models posit that diversifying selective pressure at each site remains constant throughout time, i.e. affects most lineages in the phylogenetic tree, , and there are very few cases where this assumption is biologically justified (see , , , for examples of models that allow selection to vary throughout the tree).

Which situation is an example of diversifying selection? A) A population of moths with white and grey forms lives in a forest containing trees with light and dark bark. B) Because bees prefer dark blue flowers, this color gradually becomes more dominant in a population of plants with a color ranging from light blue to dark blue. C) A population of plants develops all orange fruit instead of a
