That would be the Stabilizing Selection where there will me not a lot of genetic variation. The curve of the population allele frequency would be quite thin with the extreme being in the middle.
This type of selection would be bimodal and could be caused by industrialization, (like the moth population in England where the dark moths were favored in areas where soot had made trees nearly black, the white moths did well on the white birches in the country and the intermediate colored "speckled" individuals were poorly camoflaged in both locations.
Intentional selection by breeders would be another obvious cause of dramatic divergence in a population.
This is called stabilizing selection because it favors the mean phenotype of a population.
It is stabilizing selection
Stabilizing selection.
It's Stabilizing Selection
Stabilizing Selection
Yes.
natural selection occurs when animals need it
Natural selection requires that individuals in a population are
What population? Perhaps you mean if there were no variation for natural selection to select from.
Populations evolve, but individuals are selected. Natural selection affects individual organisms.
This type of natural selection is called stabilizing selection because the mean traits of the population are being selected for against the immediate environment.
It is stabilizing selection
Sociobiology is the application of natural selection to human society Humans are the product of natural selection at the individual level and the product of evolution at the population level, so the human generated society is influenced by the natural selection of individual humans.
natural selection occurs when animals need it
The individual is selected and the population evolves. Keep this straight and you will avoid much confusion in the future.
Natural selection does work on preexisting variations in a population. This is how the population was shaped to be the way that they currently are or were.
On the individual, or on his genes.
Natural selection requires that individuals in a population are
No, there is no genetic variation upon which natural selection can operate.
Tends to result in a population whose individuals have extreme traits is what? ----> it is directional selection
individual
What population? Perhaps you mean if there were no variation for natural selection to select from.
No, natural selection works on that genetic variation presented to it.
