If all individuals in a species are not exactly clones of each other but have small variations in the genes (traits), some will do better when the environment changes. These traits will be "favored" over other traits. More individuals will be found with the trait.

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.


What principles includes variation and competition?

Natural selection.


Why is variation important for natural selection and what are the main sources of this variation?

Without variation natural selection would have nothing to select from that would confer survivability and reproductive success. on the organisms being selected against the organisms conspecifics and the immediate environment. Mutation and sexual recombination provide the main sources of this variation that is needed to make selection work. Mutation is the variation presented that causes the real adaptive change that can lead to speciation.


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.


Can natural selection occur without variation in a population?

no there is no genetic variation 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 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.


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 resulted from a genetic variation that was favored by natural selection?

The genetic variation that was favored by natural selection led to the increased frequency of the advantageous trait in a population over time, resulting in adaptation to the environment. This can lead to improved survival and reproductive success for individuals carrying the advantageous variation.


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.


Is it possible for a population to undergo natural selection?

No, there is no genetic variation upon which natural selection can operate.
