Variation provides the raw material for natural selection to act upon, leading to the differential survival and reproduction of individuals with advantageous traits. The greater the variation within a population, the higher the potential for adaptation and evolution in response to changing environmental conditions. Variation increases the likelihood of some individuals having traits that are better suited for survival and reproduction, thereby influencing the direction of selection.

How do stabilizing and disruptive selection differ in terms of their impact on the genetic variation within a population?

Stabilizing selection maintains genetic variation by favoring the average traits, while disruptive selection increases genetic variation by favoring extreme traits.


Evolution by natural selection works best on populatin having no variation?

Evolution by natural selection actually relies on variation within a population. Without variation, there would be no genetic differences for natural selection to act upon, leading to no evolution. Variation provides the raw material for natural selection to work with, allowing beneficial traits to be favored and passed on to future generations.


What modes of selection leads to a reduction in variation but no change in the mean?

Stabilizing selection is the mode of selection that can lead to a reduction in variation without changing the mean of a trait. In this type of selection, extreme phenotypes are selected against, while intermediate phenotypes are favored, resulting in a narrower range of phenotypic variation but maintaining the same mean.


How do genetic variation and environmental factors influence evolution?

Genetic variation drives evolution by providing the raw material for natural selection to act upon, allowing organisms to adapt to changing environments. Environmental factors can influence which traits are favored, shaping the direction of evolution. Together, genetic variation and environmental factors contribute to the diversity of life on Earth through the process of evolution.


Why is genetic variation important for natural selection to drive evolution?

Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.

What do stabilization selection and disruptive selection have in common?

They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation


How does genetic variation support Natural Selection?

Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.


Is Natural selection a source of genetic variation in a population?

No, natural selection works on that genetic variation presented to it.


How does natural selection enhance or reduce the variability of a species?

Natural selection doesn't reduce variation. Variation is regulated by the rate of mutation.Natural selection reduces the chance of bad variation from being passed on and increases the chances for good variation to be passed on.


Type of selection in which human select the variation?

Artificial selection.


Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?

Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.


What characteristic within populations cause natural selection to occur?

Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.


How does genetic recombination influence how species change over time?

The genetic variation introduced during recombination provides new allelic combinations for natural selection to act upon.


What principles includes variation and competition?

Natural selection.


Can natural selection occur without variation in a population?

no there is no genetic variation for natural selection to act upon


Which type of selection tends to increase genetic variation?

Natural Selection.


How do stabilizing and disruptive selection differ in terms of their impact on the genetic variation within a population?

Stabilizing selection maintains genetic variation by favoring the average traits, while disruptive selection increases genetic variation by favoring extreme traits.
